explain phares and clauses in english grammar
A phrase is a small group of words that adds meaning to a word. A phrase is not a sentence because it is not a complete idea with a subject and a predicate and thus, doesn't make sense completely.
For instance in the following lines, the words in italics form phrases:
Tell me what to do.
The elephant leaned against the wall.
The clouds float in the sky.
It is a mistake that you have made.
He has a game of robots.
Clauses are units of grammar that contain at least one predicate (verb) and a subject. A clause, therefore, contains a single verb group. A clause is different than a phrase. A clause is a group of words with a verb and a subject.
Instances of the same can be seen in italics in the following sentences:
He has a chain which is made of gold.
The train had left by the time they reached.
I belong to a family which has fifteen members.
