Grammar TextBook category
A grammatical category is a class of units (such as noun and verb) or features (such as number and case) that share a common set of characteristics. One of the simplest ways to create grammatical categories is by grouping words together based on their class. Classes are word sets that display the same formal properties, such as inflection or verb tense.
Put another way, grammatical categories can be defined as sets of words with similar meanings (called semantics.)
- The lexical class includes: nouns, verbs, adjectives, adverbs.
- The functional class includes: determiners, particles, prepositions, modals, qualifiers, question words, conjunctions, other words denoting position or spatial relation.
Grammar groups can be further divided, depending on a word’s defining properties.
