Lexicology came into being to meet the demands of many different branches of applied linguistics, namely of lexicography, standardisation of terminology, information retrieval, literary criticism and especially of foreign language teaching.
The word, as it has already been stated, is studied in several branches of linguistics and not in lexicology only, and the latter, in its turn, is closely connected with general linguistics, the history of the language, phonetics, stylistics, grammar and such new branches of our science as sociolinguistics, paralinguistics, pragmalinguistics and some others.
The importance of the connection between lexicology and phonetics stands explained if we remember that a word is an association of a given group of sounds with a given meaning, so that top is one word, and tip is another. Phonemes have no meaning of their own but they serve to distinguish between meanings. Their function is building up morphemes, and it is on the level of morphemes that the form-meaning unity is introduced into language. We may say therefore that phonemes participate in signification.
Word-unity is conditioned by a number of phonological features. Phonemes follow each other in a fixed sequence so that [pit] is different from [tip]. The importance of the phonemic make-up may be revealed by the substitution test, which isolates the central phoneme of hope by setting it against hop, hoop, heap or hip.
Discrimination between the words may be based upon stress: the word ‘ import is recognised as a noun and distinguished from the verb im'port due to the position of stress. Stress also distinguishes compounds from otherwise homonymous word-groups: ‘ blackbird:: ‘ black ‘ bird. Each language also possesses certain phonological features marking word-limits.
Historical phonetics and historical phonology can be of great use in the diachronic study of synonyms, homonyms and polysemy. When sound changes loosen the ties between members of the same word-family, this is an important factor in facilitating semantic changes.
The words whole, heal, hail, for instance, are etymologically related. The word whole originally meant ‘unharmed’; unwounded’. The early verb whole meant 4to make whole’, hence ‘heal’. Its sense of ‘healthy’ led to its use as a salutation, as in hail! Having in the course of historical development lost their phonetic similarity, these words cannot now exercise any restrictive influence upon one another’s semantic development. Thus, hail occurs now in the meaning of ‘call’, even with the purpose to stop and arrest (used by sentinels).
Meaning in its turn is indispensable to phonemic analysis because to establish the phonemic difference between [ou] and [o] it is sufficient to know that [houp] means something different from [hop].
All these considerations are not meant to be in any way exhaustive, they can only give a general idea of the possible interdependence of the two branches of linguistics.
Stylistics, although from a different angle, studies many problems treated in lexicology. These are the problems of meaning, connotations, synonymy, functional differentiation of vocabulary according to the sphere of communication and some other issues. For a reader without some awareness of the connotations and history of words, the images hidden in their root and their stylistic properties, a substantial part of the meaning of a literary text, whether prosaic or poetic, may be lost.
Thus, for instance, the mood of despair in O. Wilde’s poem “Taedium Vitae” (Weariness of Life) is felt due to an accumulation of epithets expressed by words with negative, derogatory connotations, such as: desperate, paltry, gaudy, base, lackeyed, slanderous, lowliest, meanest.
An awareness of all the characteristic features of words is not only rewarded because one can feel the effect of hidden connotations and imagery, but because without it one cannot grasp the whole essence of the message the poem has to convey. The difference and interconnection between grammar and lexicology is one of the important controversial issues in linguistics and as it is basic to the problems under discussion in this book, it is necessary to dwell upon it a little more than has been done for phonetics and stylistics.
A close connection between lexicology and grammar is conditioned by the manifold ties between the objects of their study. Even isolated words as presented in a dictionary bear a definite relation to the grammatical system of the language because they belong to some part of speech and conform to some lexico-grammatical characteristics of the word class to which they belong. Words seldom occur in isolation. They are arranged in certain patterns conveying the relations between the things for which they stand, therefore alongside with their lexical meaning they possess some grammatical meaning. Сf. head of the committee and to head a committee.
The two kinds of meaning are often interdependent.
For example, the functions of a link verb with a predicative expressed by an adjective cannot be fulfilled by every intransitive verb but are often taken up by verbs of motion: come true, fall ill, go wrong, turn red, run dry and other similar combinations all render the meaning of ‘become sth’. The function is of long standing in English and can be illustrated by a line from A. Pope who, protesting against blank verse, wrote: It is not poetry, but prose run mad.1
On the other hand the grammatical form and function of the word affect its lexical meaning. A well-known example is the same verb “ go” when in the continuous tenses, followed by to and an infinitive (except go and come), it serves to express an action in the near and immediate future, or an intention of future action: You're not going to sit there saying nothing all the evening, both of you, are you? (Simpson). Participle II of the same verb following the link verb be denotes absence: The house is gone.
