On these pages we look at vocabulary categorised by word class (verbs, nouns, adjectives etc) and by word form (contractions, prefixes, suffixes etc). These pages deal mainly with vocabulary, for example word lists, meanings and sample sentences with the words in context. But see also the grammar of word classes.
Modern grammars normally recognise four major word classes (verb, noun, adjective, adverb) and five other word classes (determiners, preposition, pronoun, conjunction, interjection), making nine word classes (or parts of speech) in total. But note that some grammarians use different systems and may recognise eight or ten different word classes.
Verbs are action or state words like: run, work, study, be, seem
Nouns are words for people, places or things like: mother, town, Rome, car, dog
Adjectives are words that decribe nouns, like: kind, clever, expensive
Adverbs are words that modify verbs, adjectives or other adverbs, like: quickly, back, ever, badly, away generally, completely
Prepositions are words usually in front of a noun or pronoun and expressing a relation to another word or element, like: after, down, near, of, plus, round, to
Pronouns are words that take the place of nouns, like: me, you, his, it, this, that, mine, yours, who, what
Interjections have no grammatical value - words like: ah, hey, oh, ouch, um, well
Lists of suffixes and examples in use: -ation, -al, -ize
Words starting with mono- and poly-
Lists of words starting with the combining forms mono- and poly-
Shortened forms of words and phrases, common in speech: I'm, aren't, here's, gonna
