Adjectives

Adjectives change the meaning of nouns and pronouns. They tell us which, whose, what kind, and how many.

There are seven words that are always adjectives: The articles a, an, and the and the possessives my, our, your, and their.

Other pronouns can also be used as adjectives. Demonstrative pronouns, this, that, these, those; interrogative pronouns, whose, which, what; and indefinite pronouns, another, any, both, each, either, many, neither, one, other, some; when used with a noun become adjectives. Cardinal and ordinal numbers can be adjectives.

Proper nouns, possessives and modifiers made from them, and common nouns can be adjectives.

Verb forms can also be used as adjectives. They are called participial adjectives.

We change the form of the adjective when speaking of one, two, or more than two. Either add er or est to the adjective or use the words more or most before the adjective. Some adjectives are irregular and must be memorized or looked up in the dictionary. The three comparisons are positive (the base form of the adjective), comparative (comparing two), and superlative (for more than two).

One-syllable adjectives and some two-syllable adjectives (especially those ending in y or le) add er and est.

Never use double comparisons. If you use er or est, then don't use more or most.
