Here's a breakdown:
* Complex sentence: A sentence with one independent clause (a complete thought) and at least one dependent clause (a clause that cannot stand alone).
* Subordinating conjunction: A word or phrase that joins a dependent clause to an independent clause, indicating the relationship between them.
Examples of subordinating conjunctions:
* Time: after, before, since, until, when, while
* Cause/effect: because, since, so that
* Contrast: although, even though, though, whereas
* Condition: if, unless
* Purpose: in order that, so that
Example sentence:
* "I went to the store because I needed milk."
* "I went to the store" is the independent clause.
* "because I needed milk" is the dependent clause.
* "because" is the subordinating conjunction.
