Word Classes

and Word Forms

Vocabulary elements categorised by word class or part of speech (verb, noun, adjective etc), as well as by word form (contraction, prefix, suffix etc).

These pages deal mainly with vocabulary, for example word lists, meanings and sample sentences with words in use. But see also the grammar of parts of speech.

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.
