What Is an Independent Clause in English?

In English grammar, an independent clause is a group of words made up of a subject and a predicate. Unlike a dependent clause, an independent clause is grammatically complete—that is, it can stand alone as a sentence. An independent clause is also known as a main clause or a superordinate clause.

Two or more independent clauses can be joined with a coordinating conjunction (such as and or but) to form a compound sentence.

• A clause is a group of words that [contains] a subject and a verb. There are two major types: independent clauses and dependent clauses. An independent clause can stand alone as a sentence, beginning with a capital letter and ending with terminal punctuation such as a period. A dependent clause cannot stand alone as a sentence; instead, it must be attached to an independent clause."(Gary Lutz and Diane Stevenson, The Writer's Digest Grammar Desk Reference. Writer's Digest Books, 2005)

"An independent clause is one that is not dominated by anything else, and a subordinate clause is a clause that is dominated by something else. A sentence, on the other hand, can be made up of numerous independent and/or subordinate clauses, so it can't really be defined in terms of the syntactic concept of clause."
