Where in a sentence can an adjective be?

Answer 1

An adjective is a word describing a noun so usually it comes before the noun.

For example, in: He picked a green banana, banana is a noun and the adjective green comes before it.

In rare circumstances, especially in phrases from foreigh languages (like court martial, Solicitor General), the adjective may come after the noun.

Answer 2

Yes you can. Example: Dogs like to take walks. Pencils have erasers. Dogs and pencils are both nouns and they started the sentence.

Answer 3

A sentence can be started with an adjective. For instance: Large eggs were on the breakfast table when Ronald came down the stairs.

Answer 4

No, an adjective is usually a singular word that describes a noun. For example, the cheery salesperson or the silly puppy are two different forms of adjectives.
