Combining Sentences through Coordination and Subordination

What is sentence coordination? What is subordination?

Coordination and subordination are simply two strategies for showing the relationship between ideas in a sentence.

Coordination combines two ideas that are equally important.
Subordiation combines two ideas in a way that makes one idea more important than the other. The less important idea is dependent on--or subordinate to--the more important idea.

Coordination Subordination

Both strategies use conjunctions to combine independent clauses into a single sentence.
