LANGUAGE NOTE Dependent clauses A dependent clause contains a verb and a subject and is a secondary part of the sentence. It is dependent because it ‘depends’ on the main clause. A main clause can usually stand by itself as a complete sentence. A dependent clause is always joined to a main clause and cannot stand by itself as a sentence. Dependent clauses are typically joined to main clauses with certain types of words, for example: relative pronouns (e.g., who, which, that); subordinating conjunctions (e.g., if, when, before, although, whereas, that); question words (e.g., what, why). Some dependent clauses are non-finite, that is, they don’t have a full verb but a participle form instead (e.g., having finished …, thinking …), and the subject may not be stated. For more on this, see a good grammar reference book.
