7.2 Coordination and Subordination

Subordination

Subordination joins two sentences with related ideas by merging them into a main clause (a complete sentence) and a dependent clause (a construction that relies on the main clause to complete its meaning). Coordination allows a writer to give equal weight to the two ideas that are being combined, and subordination enables a writer to emphasize one idea over the other. Take a look at the following sentences:

Original sentences: Tracy stopped to help the injured man. She would be late for work.

To illustrate that these two ideas are related, we can rewrite them as a single sentence using the subordinating conjunction even though.

Revised sentence: Even though Tracy would be late for work, she stopped to help the injured man.

In the revised version, we now have an independent clause (she stopped to help the injured man) that stands as a complete sentence and a dependent clause (even though Tracy would be late for work) that is subordinate to the main clause. Notice that the revised sentence emphasizes the fact that Tracy stopped to help the injured man, rather than the fact she would be late for work. We could also write the sentence this way:

Revised sentence: Tracy stopped to help the injured man even though she would be late for work.

The meaning remains the same in both sentences, with the subordinating conjunction even though introducing the dependent clause.
