can you pls give me the definition of two word adjectives?????????????
I am sure someone will correct me if I am wrong but I don't believe there is a separate definition for two word adjectives.

An adjective is a word that describes a noun or a pronoun.

When an adjective of two or more words occurs before a noun it is normally hyphenated.

A student -focussed approach is needed.
Our approach is student focussed.

Two-word adjectives often need hyphens.
Adjectives of two words often need hyphens.

I hope this helps you.
