What is a Dependent Clause?
A clause is a group of words that contains a subject and a verb. However, not all clauses can stand alone. An independent clause expresses a complete thought and is a sentence by itself. A dependent clause (or subordinate clause) does not express a complete thought and cannot stand alone. It depends on an independent clause to makesense.
Dependent clauses often start with subordinating conjunctions such as after, although, because, before, if, since, unless, until, when, and while.
Example:
Independent: Cameron took a shower.
Dependent: After he ran.
Combined: After heran, Cameron took a shower.

Advanced Info: Types of Dependent Clauses
Dependent clauses function as different parts of speech within a complex sentence:
- Adjective Clauses: Modify a noun or pronoun. They usually begin with relative pronouns like who, whom, whose, which, or that. Example: The man who is at the door wants to see you.
- Adverb Clauses: Modify a verb, adjective, or adverb. They tell when, where, why, or how. Example: I was late because I overslept.
- Noun Clauses: Function as a noun (subject or object). Example: I don’t know what happened yesterday.
Exercise 1: Independent or Dependent? Write ‘I’ for Independent and ‘D’ for Dependent.
