Morphologically English Nouns are of 3 kinds:
· Simple
· Derived/derivative/
· Compound
Simple nouns are rootnouns that is, they consist only of one root (boy, girl, hook, chair, /
Derived nouns are built up with the help of prefixes, which are placed before the root/ prefixes/ and after the root / suffixes/: dislike, remark, artist, doctor, friendship, teacher, freedom.
Here are some of the most important suffixes of nouns: -ance, -ence, -ing, -ism, -ment, -ness --tion, -sion, -er, -or. For example: resistance, presence, meanings, agreement, decision, reali ty, speaker, musician.
Compound nouns consist of at last 2 roots. Most often the first is a noun / airman, footnote / or an adjective / blackboard, greenhouse/. There are syntactic compounds which don’t contain any noun / forget –me-not, merry-go-round/
The category of number
1. The plural of a noun is usually made by adding s to the singular: day- days, dog- dogs, house-houses s is pronounced /s/ after a p, k or f sound. Otherwise it is pronounced /z/. When s is placed after ce, ge, se or ze an extra syllable (/iz/) is added to the spoken word.
2. Nouns ending in o or ch, sh. ss or x form their plural by adding es: tomato- tomatoes, brush- brushes, box- boxes, church- churches, kiss- kisses.
But words of foreign origin or abbreviated words ending in o add s only: dynamo-dynamos, kimono-kimonos, piano-pianos,kilo-kilos, photo- photos, soprano-sopranos.
