Compound-complex sentences-  moving from simple to advanced sentence structures


Switching between independent and dependent clauses will develop the way you express yourself. These are known as compound and complex sentences.

Compound sentence: two independent clauses connected by a conjunction, FANBOYS: for, and, nor, but, or, yet, so.

Complex sentence: at least one dependent clause and an independent clause with a connected with a subordinate conjunction: although, after, while, when, unless, because, before, if, since.


Let's look at some examples, shall we?


Start with two independent clauses, for example:

The frog leapt into the lake. The water rippled.

Combine the independent clauses into a compound sentence using FANBOYS:

The frog leapt into the lake and the water rippled.

Add a dependent clause before, in middle of, or at the end of the two independent clauses. This  creates a compound-complex sentence:

Because the frog was chased by a bird, the frog leapt into the lake and the water rippled.

The frog leapt into the lake and the water rippled, because the frog was chased by a bird.

I read and after eating, I watched tv.
