In order to introduce a subordinate clause, you must use a subordinating conjunction, also known as a subordinator. Some subordinators include when, whenever, if, because, while, and unless.
Below are three examples of subordinate clauses, which are italicized for emphasis.
1) You should proofread your essays because demonstrating that you have strong writing skills is essential to a high grade.
2) Whenever my English teacher grades our papers, she checks for correct subject-verb agreement.
3) I submitted my final essay several hours before the deadline, although I was tempted to procrastinate and finish it later.
However, subordinate clauses can obscure sentence meanings when they are placed inappropriately. Be sure that your subordinate clause does not disrupt the logic and flow of your independent clause.
