Clauses

Learn about independent and dependent clauses and how they form sentences

What Are Clauses?

A clause is a group of words that contains a subject and a predicate. Clauses are the building blocks of sentences and can be either independent (complete thoughts) or dependent (incomplete thoughts). Understanding clauses helps you write more complex and varied sentences.
