An adjective is a word or set of words that describe or modify nouns or pronouns. Adjectives add information by describing people, places, or things in a sentence. You can use them to describe people, objects, and situations to make the listener understand your point of view.
Nouns are ordinarily very general and indefinite in meaning, for example, man conveys only a very general idea. To make that idea definite we need the help of one or more descriptive words such as short, tall, stout, good.
- Brett Lee is a fast bowler.
- Angelina Jolie is very beautiful.
- Where are your books?
- We go on a holiday every year.
- English is a difficult subject.
- She bought an expensive house.
The highlighted words in the above sentences add to the meanings of the nouns following them. Therefore, they are all adjectives.
