Answer 1

A phrase is something that adds meaning to your word. It doesn’t make sense completely because it is not a sentence.
For example, Tell me what to do.

The units of grammar that contains at least one verb and a subject is known as clause. 
She has a beautiful ring which is made of stones.
My cousin belongs to a family which has 5 members.
