THE PHRASE AND THE CLAUSE

Such a group of words, which makes sense, but not complete sense, is called a Phrase.

In the following sentences, the groups of words in italics are Phrases:

Humpty Dumpty sat on a wall.

Examine the groups of words in italics in the following sentences:
He has a chain of gold.
He has a chain which is made of gold.
We recognize the first group of words as a Phrase.

Such a group of words forms part of a sentence and contains a Subject and a
Predicate, is called a Clause.

In the following sentences, the groups of words in italics are Clauses:
People who pay their debts are trusted.
