A similar analysis on the word-formation level showing not only the morphemic constituents of the word but also the structural pattern on which it is built.
The analysis of word-structure at the morphemic level must proceed to the stage of Ultimate Constituents. For example, the noun friendliness is first segmented into the ICs: [frendlı-] recurring in the adjectives friendly- looking and friendly and [-nıs] found in a countless number of nouns, such as unhappiness, blackness, sameness, etc. the IC [-nıs] is at the same time an UC of the word, as it cannot be broken into any smaller elements possessing both sound-form and meaning. Any further division of ness would give individual speech-sounds which denote nothing by themselves. The IC [frendlı-] is next broken into the ICs [-lı] and [frend-] which are both UCs of the word.
Morphemic analysis under the method of Ultimate Constituents may be carried out on the basis of two principles: the so-called root-principle and affix principle.
According to the affix principle the splitting of the word into its constituent morphemes is based on the identification of the affix within a set of words, e.g. the identification of the suffix er leads to the segmentation of words singer, teacher, swimmer into the derivational morpheme er and the roots teach-, sing-, drive-.
According to the root-principle, the segmentation of the word is based on the identification of the root-morpheme in a word-cluster, for example the identification of the root-morpheme agree- in the words agreeable, agreement, disagree.
As a rule, the application of these principles is sufficient for the morphemic segmentation of words.
However, the morphemic structure of words in a number of cases defies such analysis, as it is not always so transparent and simple as in the cases mentioned above. Sometimes not only the segmentation of words into morphemes, but the recognition of certain sound-clusters as morphemes become doubtful which naturally affects the classification of words. In words like retain, detain, contain or receive, deceive, conceive, perceive the sound-clusters [rı-], [dı-] seem to be singled quite easily, on the other hand, they undoubtedly have nothing in common with the phonetically identical prefixes re-, de- as found in words re-write, re-organize, de-organize, de-code. Moreover, neither the sound-cluster [rı-] or [dı-], nor the [-teın] or [-sı:v] possess any lexical or functional meaning of their own. Yet, these sound-clusters are felt as having a certain meaning because [rı-] distinguishes retain from detain and [-teın] distinguishes retain from receive.
It follows that all these sound-clusters have a differential and a certain distributional meaning as their order arrangement point to the affixal status of re-, de-, con-, per- and makes one understand -tain and ceive as roots. The differential and distributional meanings seem to give sufficient ground to recognize these sound-clusters as morphemes, but as they lack lexical meaning of their own, they are set apart from all other types of morphemes and are known in linguistic literature as pseudo- morphemes. Pseudo- morphemes of the same kind are also encountered in words like rusty-fusty.

Derivational level of analysis. Stems. Types of Stems. Derivational types of word.
The morphemic analysis of words only defines the constituent morphemes, determining their types and their meaning but does not reveal the hierarchy of the morphemes comprising the word. Words are no mere sum totals of morpheme, the latter reveal a definite, sometimes very complex interrelation. Morphemes are arranged according to certain rules, the arrangement differing in various types of words and particular groups within the same types. The pattern of morpheme arrangement underlies the classification of words into different types and enables one to understand how new words appear in the language. These relations within the word and the interrelations between different types and classes of words are known as derivative or word- formation relations.
The analysis of derivative relations aims at establishing a correlation between different types and the structural patterns words are built on. The basic unit at the derivational level is the stem.
The stem is defined as that part of the word which remains unchanged throughout its paradigm, thus the stem which appears in the paradigm (to) ask (), asks, asked, asking is ask-; thestem of the word singer (), singers, singers, singers is singer-. It is the stem of the word that takes the inflections which shape the word grammatically as one or another part of speech.
The structure of stems should be described in terms of ICs analysis, which at this level aims at establishing the patterns of typical derivative relations within the stem and the derivative correlation between stems of different types.
There are three types of stems: simple, derived and compound.
Simple stems are semantically non-motivated and do not constitute a pattern on analogy with which new stems may be modeled. Simple stems are generally monomorphic and phonetically identical with the root morpheme. The derivational structure of stems does not always coincide with the result of morphemic analysis. Comparison proves that not all morphemes relevant at the morphemic level are relevant at the derivational level of analysis. It follows that bound morphemes and all types of pseudo- morphemes are irrelevant to the derivational structure of stems as they do not meet requirements of double opposition and derivative interrelations. So the stem of such words as retain, receive, horrible, pocket, motion, etc. should be regarded as simple, non- motivated stems.
Derived stems are built on stems of various structures though which they are motivated, i.e. derived stems are understood on the basis of the derivative relations between their ICs and the correlated stems. The derived stems are mostly polymorphic in which case the segmentation results only in one IC that is itself a stem, the other IC being necessarily a derivational affix.
Derived stems are not necessarily polymorphic.
Compound stems are made up of two ICs, both of which are themselves stems, for example match-box, driving-suit, pen-holder, etc. It is built by joining of two stems, one of which is simple, the other derived.

|
|
In more complex cases the result of the analysis at the two levels sometimes seems even to contracted one another.
The derivational types of words are classified according to the structure of their stems into simple, derived and compound words.
Derived words are those composed of one root- morpheme and one or more derivational morpheme.
Compound words contain at least two root- morphemes, the number of derivational morphemes being insignificant.
Derivational compound is a word formed by a simultaneous process of composition and derivational.
Compound words proper are formed by joining together stems of word already available in the language.
6. Derivative Structure
The analysis of the morphemic composition of words defines the ultimate meaningful constituents (UCs), their typical sequence and arrangement, but it does not reveal the hierarchy of morphemes making up the word, neither does it reveal the way a word is constructed, nor how a new word of similar structure should be understood. The morphemic analysis does not aim at finding out the nature and arrangement of ICs which underlie the structural and the semantic type of the word, e.g. words unmanly and discouragement morphemically are referred to the same type as both are segmented into three UCs representing one root, one prefixational and one suffixational morpheme. However the arrangement and the nature of ICs and hence the relationship of morphemes in these words is different in unmanly the prefixational morpheme makes one of the ICs, the other IC is represented by a sequence of the root and the suffixational morpheme and thus the meaning of the word is derived from the relations between the ICs un- and manly- (not manly), whereas discouragement rests on the relations of the IC discourage- made up by the combination of the. prefixational and the root-morphemes and the suffixational morpheme -ment for its second IC (smth that discourages). Hence we may infer that these three-morpheme words should be referred to different derivational types: unmanly to a prefixational and discouragement to a suffixational derivative.
The nature, type and arrangement of the ICs of the word are known as its derivative structure. Though the derivative structure of the word is closely connected with its morphemic or morphological structure and often coincides with it, it differs from it in principle.
7. Derivative Relations
According to the derivative structure all words fall into two big classes: simplexes or simple, non-derived words and complexes or derivatives. Simplexes are words which derivationally cannot be segmented into ICs. The morphological stem of simple words, i.e. the part of the word which takes on the system of grammatical inflections is semantically non-motivated and independent of other words, e.g. hand, come, blue, etc. Morphemically it may be monomorphic in which case its stem coincides with the free root-morpheme as in, e.g., hand, come, blue, etc. or polymorphic in which case it is a sequence of bound morphemes as in, e.g., anxious, theory, public, etc.
Derivatives are words which depend on some other simpler lexical items that motivate them structurally and semantically, i.e. the meaning and the structure of the derivative is understood through the comparison with the meaning and the structure of the source word. Hence derivatives are secondary, motivated units, made up as a rule of two ICs, i.e. binary units, e.g. words like friendliness, unwifely, school-masterish, etc. are made up of the ICs friendly + -ness, un- + wifely, schoolmaster+-ish. The ICs are brought together according to specific rules of order and arrangement preconditioned by the system of the language. It follows that all derivatives are marked by the fixed order of their ICs.
The basic elementary units of the derivative structure of words are: derivational bases, derivational affixes and derivational patterns which differ from the units of the morphemic structure of words (different types of morphemes). The relationsbetween words with a common root but of different derivative structure are known as derivative relations. The derivative and derivative relations make the subject of study at the derivational level of analysis; it aims at establishing correlations between different types of words, the structural and semantic patternswords are built on, the study also enables one to understand how new words appear in the language.

The constituents of the derivative structure are functional units, i.e. units whose function is to indicate relationship between different classes of words or differently-behaving words of the same class and to signal the formation of new words. It follows that derivational functions are proper to different linguistic units which thus serve as ICs of a derivative. It must be also noted that the difference between classes of words is signalled by both the derivative structure of the word, or to be more exact by the stem it shapes, and by the set of paradigmatic inflections that this structure presupposes. For example, the nominal class of words to which derivatives like historian, teacher, lobbyist are referred is signalled by both the derivative structure, i.e. the unity of their ICs history+-ian, teach+ + -er lobby + -ist shaping the stems of these words and the nominal set of paradigmatic inflections which these stems precondition, i.e. histori-an(O), historian(s), historian('s), historian(s). The class of words like enrich, enlarge is likewise signalled by their derivative structure (en- + +rich, en-+large) and the verbal set of paradigmatic inflexions. Hence the paradigmatic systems of different classes of words have, among their functions, the function of distinguishing the formal make-up of word classes. It follows that the paradigmatic system of inflections in cases of meaningful absence of the 1which determines the class membership of the motivated stem functions as the sole indication of its derived nature.
8. Derivational Bases
A derivational base as a functional unit is defined as the constituent to whom a rule of word-formation is applied. It is the part of the word which establishes connection with the lexical unit that motivates the derivative and determines its individual lexical meaning describing the difference between words in one and the same derivative set, for example the individual lexical meaning of words like singer, rebuilder, whitewasher, etc. which all denote active doers of action, is signalled by the lexical meaning of the derivational bases sing-, rebuild-, whitewash- which establish connection with the motivating source verb.
Structurally derivational bases fall into three classes: 1) bases that coincide with morphological stems of different degrees of complexity, e.g. dutiful, dutifully; day-dream, to day-dream, daydreamer; 2) bases that coincide with word-forms; e.g. paper-bound, unsmiling, unknown; 3) bases that coincide with word-grups of different degrees of stability, e,g. second-rateness, flat-waisted, etc.
1. Bases built on stems of different degree of complexity make the largest and commonest group of components of derivatives of various classes, e.g. un-button, girl-ish; girlish-ness, colour-blind-ness, ex-filmstar, etc. Bases of this class are functionally and semantically distinct from all kinds of stems. Functionally, the morphological stem is the part of the word which is the starting point for its forms; it is thepart which semantically presents a unity of lexical and functional meanings thus predicting the entire grammatical paradigm. The stem remains unchanged throughout all word-forms; it keeps them together preserving the identity cf the word. Thus the stems in the above-given words are ex-filmstar, unbutton which remain unchanged in all the forms of each word as, e.g., ex-filmstar(O), ex-filmstar(s), ex-filmstar(s), ex-filmstar(s). Stems are characterised by a phonetic identity with the word-form that habitually represents the word as a whole (the common case singular, the infinitive, etc.).

A derivational base unlike a stem does not predict the part of speech of the derivative, it only outlines a possible range and nature of the second IC and it is only the unity of both that determines the lexical-grammatical class of the derivative. A derivational base is the starting-point for different words and its derivational potential outlines the type and scope of existing words and new creations. The nominal base for example, hand- gives rise to nouns, e.g. hand-rail, hand-bag, shorthand, handful, to adjectives, e.g. handy, or verbs, e.g. to hand. Similarly the base rich- may be one of the ICs of the noun richness, the adjective gold-rich, or the verb to enrich.
Semantically the stem stands for the whole semantic structure of the word; it represents all its lexical meanings. A base, semantically, is also different in that it represents, as a rule, only one meaning of the source word or its stem. The derivatives glassful and glassy, e.g., though connected with the stem of the same source word are built on different derivational bases,, as glassful is the result of the application of the word-formation rule to the meaning of the source word drinking vessel or its contents, whereas glassy to the meaning hard, transparent, easily-broken substance. Derivatives fiery, fire-place, to fire, fire-escape, firearm, all have bases built on the stem of the same source noun fire, but the words like fire-escape fire-engine and fire-alarm are semantically motivated by the meaning destructive burning, the words firearms, ceasefire, (to) fire are motivated by another meaning shooting, whereas the word fiery (as in fiery speech, eyes) is motivated by the meaning strong emotion, excited feeling. The same difference can be exemplified by the words starlet, starry, starlike, starless which are all motivated by the derivational base meaning a heavenly body seen in the night as distant point of light, as compared to stardom, starlet, to star motivated by the base meaning a person famous as actor, singer though both represent the same morphological stem of the word star.
Stems that serve as this class of bases may themselves be different morphemically and derivationally thus forming derivational bases of different degrees of complexity which affects the range and scope of their collocability and their derivational capacity. Derivationally the stems may be:
a) simple, which consist of only one, semantically nonmotivated constituent. The most characteristic feature of simple stems in Modern English is the phonetic and graphic identity with the root-morpheme and the word-form that habitually represents the word as a whole.
As has been mentioned elsewhere simple stems may be both monomorphic units and morphemic sequences made up of bound and pseudo-morphemes, hence morphemically segmentable stems in such words as pocket, motion, retain, horrible, etc. should be regarded as derivationally simple.
b) derived stems are semantically and structurally motivated, and are the results of the application of word-formation rules; it follows that they are as a rule binary, i.e. made up of two ICs, and polymorphic, e.g. the derived stem of the word girlish is understood on the basis of derivative relations between girl and girlish; the derived stem of a greater complexity girlishness is based on the derivative relations between girlish and girlishness. This is also seen in to weekend, to daydream which is derived from the nouns week-end and day-dream and is motivated by the derivative relations between the noun and the verb.
Derived stems, however, are not necessarily polymorphic.
It especially concerns derivatives with a zero IC, i.e. meaningful absence of the derivational means in which case the distinction between the stem of the source word and the motivated stem of the derivative is signalled by the difference in paradigmatic sets of inflections which they take.
For example, the stem of the verb (to) parrot, though it consists of one overt constituent and is a one-morpheme word, should be considered derived as it is felt by a native speaker as structurally and semantically dependent on the simple stem of the noun parrot and because it conveys a regular relationship between these two classes of words verbs and nouns. The same is true of the stems in such words as (to) winter, a cut, a drive, etc.

|
|
c) compound stems are always binary and semantically motivated, but unlike the derived stems both ICs of compound stems are stems themselves. The derivative structure and morphemic composition of each IC may be of different degree of complexity, for example, the compound stem of the noun match-box consists of two simple stems, the stem of the noun letter-writer of one simple and one derived stem, and the stem aircraft-carrier of a compound and derived stem.
The structural complexity of the derivational bases built on derived and compound stems is a heavy constraint imposed on the collocability and semantic freedom of these bases and consequently on their derivative potential. Compare, for example, the derivational capacity of the simple stem girl, which can give rise to girly, girlish, girlless, girl-friend, and the limited capacity of girlish which gives only girlishness and girlishly.
2. The second class of derivational bases is made up of word-forms. It is obvious that word-forms functioning as parts of the word lose all syntactic properties they possess in independent use. This class of bases is confined to verbal word-forms the present and the past participles which regularly function as ICs of non-simple adjectives, adverbs and nouns. The collocability of this class of derivational bases is confined tojust a few derivational affixes such as the prefix un-, the suffix -ly, in e.g. unnamed, unknown, unwrapped, etc., smilingly, knowingly, etc. The derivational bases in question may be also collocated with other bases which coincide only with nominal and adjectival stems, e.g. mockingbird, dancing-girl, ice-bound, time-consuming, ocean-going, easy-going, etc.
3. The third class of derivational bases is made up of word-groups. Free word-groups make up the greater part of this class of bases. Like word-forms, word-groups serving as derivational bases lose their morphological and syntactic properties proper to them as self-contained lexical units. Bases of this class also allow of a rather limited range of collocability, they are most active with derivational affixes in the class of adjectives and nouns, e.g. in words like blue-eyed, long-fingered, old-worldish, dogooder, second-rateness, etc.
Thus, we may conclude that each class of bases, though it makes use of one of the structural units of vocabulary, is distinct from it and differs from it both in form and meaning. The greater the degree of structural complexity of the base the more limited its derivative potential.
9. Derivational Affixes
Derivational affixes are ICs of numerous derivatives in all parts of speech. Derivational affixes differ from affixational morphemes in their function within the word, in their distribution and in their meaning. Derivational affixes possess two basic functions: 1) that of stem-building which is common to all affixational morphemes: derivational and non-derivational. It is the function of shaping a morphemic sequence, or a word-form or a phrase into the part of the word capable of taking a set of grammatical inflections and is conditioned by the part-of-speech meaning these morphemes possess; 2) that of word-building which is the function of repatterning a derivational base and building a lexical unit of a structural and semantic type different from the one represented by the source unit. The repatterning results in either transferring it into the stem of another part of speech or transferring it into another subset within the same part of speech. For example, the derivational suffix -ness applied to bases of different classes shapes derived stems thus making new words. In kindliness, girlishness, etc. it repatterns the adjectival stems kindly-, girlish-, in second-rate-ness, allatonceness it turns the phrases second rate, all at once into stems and consequently forms new nouns. In most cases derivational affixes perform both functions simultaneously shaping derived stems and marking the relationship between different classes of lexical items. However, certain derivational affixes may in individual sets of words perform only one function that of stem-building. The derivational suffix -ic for example performs both functions in words like historic, economic, classic as it is applied to bases history-, economy-, class- and forms stems of words of a different part of speech. But the same suffix -ic in public, comic, music performs only its stem-building function shaping in this case a simplestem. The same is true of the suffix -ous in such words as joyous, courageous, famous as compared with anxious, conscious, curious. Stem-building is the common function shared by both derivational and non-derivational morphemes, but with the non-derivational morphemes it is the only structural function. Besides, the non-derivational affixes shape only simple stems, for example, the morpheme -id in stupid, rapid, acid, humid; the morpheme -ish in publish, distinguish, and languish. It follows that non-derivational morphemes are not applied to stems, but only to root-morphemes or morpheme sequences.
Semantically derivational affixes are characterised by a unity of part-of-speech meaning, lexical meaning and other types of morphemic meanings unlike non-derivational morphemes which, as a rule, lack the lexical type of meaning. It is true that the part-of-speech meaning is proper in different degrees to the derivational suffixes and prefixes. It stands out clearly in derivational suffixes but it is less evident in prefixes; some prefixes lack it altogether, in others it is very vague and in this case it finds expression in the fact that these prefixes tend to function in either nominal or verbal parts of speech. Prefixes like en-, un-, de-, out-, be-, unmistakably possess the part-of-speech meaning and function as verb classifiers when they make an independent IC of the derivative, e.g. deice, unhook, enslave; derivational prefixes a-, un-possess the adjectival part-of-speech meaning, e.g. unhesitating, unknown, unkind, etc., amoral, asynthetic, asymmetric, etc. In prefixes -, under-, mis- this type of meaning is vague but they tend to be active in one part of speech only: - in nominal parts of speech (i.e. nouns and adjectives), e.g. copilot, co-star, co-president; mis- and under- are largely verbal prefixes, e.g. underwork, underdo, underfeed, etc. The prefix over-evidently lacks the part-of-speech meaning and is freely used both for verbs and adjectives; the same may be said about non-, pre-, post-. The lexical meaning in derivational affixes also has its peculiarities and may be viewed at different levels.
The lexical (denotational) meaning of a generic type proper mostly not to an individual affix but to a set of affixes, forming a semantic subset such as, for example, the meaning of resemblance found in suffixes -ish, -like, -y, -ly (spiderish, spiderlike, spidery); the causative meaning proper to the prefix en- (enslave, enrich), the suffixes ise (-ize), -(i)fy (brutalise, formalise, beautify, simplify, etc.); the meaning of absence conveyed by the prefix un- and the suffix -less; the meaning of abstract quality conveyed by the suffixes -ness, -ity, etc.
On the other hand derivational affixes possess another type of lexical meaning an individual meaning shared by no other affix and thus distinguishing this particular affix from all other members, of the same semantic group. For example, suffixes -ish, -like, -y all have the meaning of resemblance, but -like conveys an overall resemblance,-ish conveys likeness to the inner, most typical qualities of the object, -y in most cases conveys likeness to outer shape, form, size of the object. Suffixes -er, -ist both possess the meaning of the agent, but the distinguishing feature of the suffix -er is that it conveys the meaning of the active doer (animate or inanimate), whereas -ist conveys the meaning of profession (flutist, biologist) and followers of principles and beliefs (socialist, leftist) and thus has the meaning only of human beings. Derivational affixes semantically may be both mono- and polysemantic.
Derivational affixes are highly selective and each is applied to a specific set of bases which is due to the distributional type of meaning found in all affixes. All affixes are selective as to the structural peculiarities of bases (their morphemic, derivational, phonological and etymological features), some in addition are highly responsive to the lexical-semantic properties of the bases they are collocated with. For example, the adjectival suffix -able is collocated with verbal bases with practically no semantic constraints imposed on them. On the other hand the adjective-forming suffix -ful1 is restricted in its collocability to nominal bases of abstract meaning (useful, beautiful), while its homonym the noun-forming -ful2 also collocating with nominal bases chooses bases of concrete meaning and within this class only nouns which have in their semantic structure a semantic component container (chestful, lungful, bagful).
10. Semi-Affixes
There is a specific group of morphemes whose derivational function does not allow one to refer them unhesitatingly either to the derivational affixes or bases. In words like half-done, half-broken, half-eaten and ill-fed, ill-housed, ill-dressed the ICs half- and ill- are given in linguistic literature different interpretations: they are described both as bases and as derivational prefixes. The comparison of these ICs with the phonetically identical stems in independent words ill and half as used in such phrases as to speak ill of smb, half an hour ago makes it obvious that in words like ill-fed, ill-mannered, half-done the ICs ill- and half- are losing both their semantic and structural identity with the stems of the independent words. They are all marked by a different distributional meaning which is clearly revealed through the difference of their collocability as compared with the collocability of the stems of the independently functioning words. As to their lexical meaning they have become more indicative of a generalising meaning of incompleteness and poor quality than the individual meaning proper to the stems of independent words and thus they function more as affixational morphemes similar to the prefixes out-, over-, under-, semi-, mis- regularly forming whole classes of words. Besides, the high frequency of these morphemes in the above-mentioned generalised meaning in combination with the numerous bases built on past participles indicates their closer ties with derivational affixes than bases. Yet these morphemes retain certain lexical ties with the root-morphemes in the stems of independent words and that is why are felt as occupying an intermediate position, as morphemes that are changing theirlass membership regularly functioning as derivational prefixes but still retaining certain features of root-morphemes. That is why they are sometimes referred to as semi-affixes. To this group we should also refer well- and self- (well-fed, well-done, self-made), -man in words like postman, cabman, chairman, -looking in words like foreign-looking, alive-looking, strange-looking, etc.
11. Derivational Patterns
Neither bases nor affixes alone can predict all the structural and semantic properties of words the ICs of which they may be. It is the combination of bases and affixes that makes up derivatives of different structural and semantic classes. Both bases and affixes due to the distributional meaning they possess show a high degree of consistency in their selection and are collocated according to a set of rules known as derivational patterns. A derivational pattern is a regular meaningful arrangement, a structure that imposes rigid rules on the order and the nature of the derivational bases and affixes that may be brought together. A pattern is a generalisation, a scheme indicative of the type of ICs, their order and arrangement which signals the part of speech, the structural and semantic peculiarities common to all the individual words for which the pattern holds true. Hence the derivational patterns (DP) may be viewed as classifiers of non-simple words into structural types and within them into semantic sets and subsets. DPs are studied with the help of distributional analysis at different levels. Patterns of derivative structures are usually represented in a generalised way in terms of conventional symbols: small letters v, n, a, d, stand for the bases which coincide with the stems of the respective parts of speech: verbs, nouns, adjectives, adverbs, numerals; ved, ving stand for the bases which are the past and present participles respectively. In words of the long-fingered or sit-inner type the derivational bases are represented by bracketed symbols of the parts of speech making up the corresponding collocations, for example (a+n)+ +-ed), (v+d) + er.
DPs may represent derivative structure at different levels of generalisation:
at the level of structural types specifying only the class membership of ICs and the direction of motivation, such as a+-sf -> N, prf- + +n -> V, prf- n -> N, n + -sf -> N, n + -sf -> V, etc. In terms of patterns of this type, known as structural formulas,1 all words may be classified into four classes: suffixal derivatives, e.g. friendship, glorified, blackness, skyward; prefixal derivatives, e.g. rewrite, exboxer, non-smoker, un-happy, etc.; conversions, e.g. a cut, to parrot, to winter, etc.; compound words key-ring, music-lover, wind-driven, etc. But derivational formulas are not indicative either of any one lexical-grammatical or lexical class of words, as, for example, the formula a + -sf may equally represent suffixal nouns as in blackness, possibility and verbs, as in sharpen, widen, or adjectives as in blackish.
derivative structure and hence derivative types of words may be represented at the level of structural patterns which specify the baseclasses and individual affixes thus indicating the lexical-grammatical and lexical classes of derivatives within certain structural classes of words. DPs of this level are based on the mutual interdependence of individual affixes and base classes and may be viewed in terms of each. The suffixes refer derivatives to specific parts of speech and lexical subsets as, for example, v + -er -> N signals that the derivatives built on this pattern are de-verbal nouns which represent a semantic set of active agents, denoting both animate and inanimate objects, e.g. reader, runner, singer, unlike, for example, denominal nouns with the underlying pattern +-r -> N which stands for agents denoting residents or occupations, e.g. Londoner, villager, gardener. The DP n+-ish -> A signals a set of adjectives with the lexical meaning of resemblance, whereas a + -ish -> A signals adjectives meaning a small degree of quality, etc.
c) DPs may be specified as to the lexical-semantic features of both ICs. DPs of this level specify the semantic constraints imposed upon the set of derivatives for which the pattern is true and hence the semantic range of the pattern. For example, the nominal bases in the pattern n+-ess -> N are confined to nouns having in their semantic structures a component a male animate being, e.g. lioness, traitress, stewardess, etc.; the nominal bases in n+-ful2 -> N are limited by nouns having a semantic component container, e.g. lungful, carful, mouthful, whereas in n+ -ful1 -> A the nominal bases are confined to nouns of abstract meaning. The same is true of the pattern n + -y -> A which represents different semantic sets of derivatives specified by semantic constraints imposed on both the bases and the suffix: nominal bases denoting living beings are collocated with the suffix -y meaning resemblance, e.g. birdy, spidery, catty, etc., but nominal bases denoting material, parts of the body attract another meaning of the suffix -y that of considerable amount, size resulting in the adjectives like powdery, grassy, leggy, starry, etc.
It follows that derivational patterns may be classified into two types structural pattern (see b, above) and structural-semantic pattern (see c).
12. Derivational Types of Words
According to their derivational structure words fall into two large classes: simple, non-derived words or simplexes and derivatives or complexes. Complexes are classified according to the type of the underlying derivational pattern into: derived and compound words. Derived words fall into affixational words, which in their turn must be classified into suffixal and prefixal derivatives, and conversions. Each derivational type of words is unequally represented in different parts of speech.
Comparing the role each of these structural types of words plays in the language we can easily perceive that the clue to the correct understanding of their comparative value lies in a careful consideration of 1) the importance of each type in the existing word-stock and 2) their frequency value in actual speech. Of the two factors frequency is by far the most important. According to the available word counts in different parts of speech, we find that derived words numerically constitute the largest class of words in the existing word-stock, derived nouns comprise approximately 67% of the total number and adjectives about 86%, whereascompound nouns make about 15% and adjectives only about 4%. Simple words come to 18% in nouns, i.e. a trifle more than the number of compound words; in adjectives simple words come to approximately 12%.But if we now consider the frequency value of these types of words in actual speech, we cannot fail to see that simple words occupy a predominant place in English. According to recent frequency counts, about 60% of the total number of nouns and 62% of the total number of adjectives in current use are simple words. Of the total number of adjectives and nouns, derived words comprise about 38% and 37% respectively while compound words comprise an insignificant 2% in nouns and 0.2% in adjectives.2 Thus it is the simple, non-derived words that constitute the foundation and the backbone of the vocabulary and that are of paramount importance in speech. It should also be mentioned that non-derived words are characterised by a high degree of collocability and a complex variety of meanings in contrast with words of other structural types whose semantic structures are much poorer. Simple words also serve as basic parent forms motivating all types of derived and compound words. At the same time it should be pointed out that new words that appear in the vocabulary are mostly words of derived and compound structure.
