Which statement accurately describes a dependent clause?

A dependent clause is accurately described as a segment of a sentence that cannot stand alone as a complete sentence. It usually begins with a subordinating conjunction (like because, although, or while) or a relative pronoun (like who, which, or that), which indicates that it is reliant on an independent clause to provide a complete thought.

For example, in the sentence "Although she was tired," the clause "Although she was tired" introduces an idea but does not form a full, standalone sentence. It leaves the reader waiting for additional information—indicating the clause’s dependence on another clause to make sense.

In contrast, a complete thought requires both a subject and a predicate and can stand independently, which a dependent clause cannot do. While some of the other options touch on aspects of clauses, they do not accurately capture the defining characteristic of a dependent clause, which is its inability to stand on its own.
