Word classes

Word classes

English words fall into 8 grammatical word classes (known in traditional grammar as ‘parts of speech’). They form 2 large subgroups:

  • Open classes include nouns, verbs, adjectives and adverbs. Open classes continue to grow as new words are coined and taken up by writers and speakers.
  • Closed classes include prepositions, conjunctions, pronouns and determiners (ie structural words that glue words and phrases together in clauses and sentences). Closed classes are rarely added to, and additions are often resisted.

Each word class has subtypes with different grammatical functions.

A noun is the name of something (such as a person, animal, place, thing, feeling or action) aunt     possum     valley     sadness     running
Common nouns define a type of thing (concrete or abstract)

Modal verbs (eg can, may, will) add speaker attitudes or speaker intentions to verb phrases

Descriptive adjectives provide descriptive information blue     large     joyful
Categorial adjectives define and specify Greek     wooden     antique
