Important Notes:
* This list is not exhaustive. There are other less common subordinating conjunctions, such as "lest," "provided that," and "in case."
* Some words can act as both subordinating conjunctions and other parts of speech, depending on the context. For example, "while" can be a conjunction (e.g., "While I was eating, the phone rang") or a noun (e.g., "The test took a while").
* Remember: Subordinating conjunctions join a dependent clause (which cannot stand alone) to an independent clause (which can stand alone). They create complex sentences.
