Here are some examples of subordinating conjunctions:
* Time: after, before, since, until, when, while
* Cause and effect: because, since, so that
* Contrast: although, though, even though
* Condition: if, unless
* Purpose: in order that, so that
* Comparison: as, than
For example:
* Because the weather was bad, we stayed inside. (Subordinating conjunction "because" introduces the subordinate clause "the weather was bad")
* While I was walking, I saw a dog. (Subordinating conjunction "while" introduces the subordinate clause "I was walking")
* If you go to the store, could you buy some milk? (Subordinating conjunction "if" introduces the subordinate clause "you go to the store")
