Subordinating conjunctions are used to give extra information. They start a dependent clause or a clause which is incomplete. For example, the following sentence is incomplete.

  • *When I’m older.

Remember when using subordinating conjunctions, you need to have an independent clause attached to your dependent clause. The following is a complete sentence:

  • When I’m older I want to move to Spain.

Here is a list of common subordinating conjunctions (the dependent clauses are underlined):
