What is the difference between a subordinate clause and a clause?

A subordinate clause is a group of words that contains a subject and a predicate, but it is not a complete sentence. A clause, on the other hand, is a group of words that contains a subject and a predicate, and it is a complete sentence.

Here is an example of a subordinate clause:

The dog barked at the mailman.

Here is an example of a clause:

The dog barked at the mailman.

In the first example, the subordinate clause is a group of words that contains a subject (the dog) and a predicate (barked at). In the second example, the clause is a complete sentence that contains a subject (the dog) and a predicate (barked at).
