Here are some notes about adjectives:

1. When the predicate describes the subject, the verb is one of the five sens es, or is a linking verb ( to be, seem , become, appear) use an adjective:

The weather turned nasty.

I feel sad.

He became furious.

2. A descriptive adjective tells us the quality or the condition of the noun or pronoun:

A short man

The excited dog

A hot meal
