Compound Sentence: Sentence Structure

Let’s learn about compound sentence structure.

We’ve been taught since pre-school that the basic parts of a sentence are its subject and verb. Taking that to heart, let’s delve into the different kinds of structure – the simple, compound, complex, and compound-complex. Why do you need to learn these? Because the plain existence of a subject and a verb in a sentence isn’t enough to fuel a message. Using varying kinds of sentences makes your writing – and speaking – more intelligent and compelling.

What is a Compound Sentence?

A compound sentence has two or more independent clauses but no subordinate clause. These independent clauses are usually joined by coordinating conjunctions which we discussed earlier. Remember the mnemonic device FANBOYS? They’re the most commonly used coordinating conjunctions: for, and, nor, but, or, yet, and so – spot them in the examples below. Remember to use a comma before a coordinating conjunction that connects two independent clauses.

  • Becky baked too many cookies, yet she did not give me any. [two independent clauses joined by the conjunction yet]
  • Chris writes love letters to Marissa every day, but she never reads them. [two independent clauses joined by the conjunction but]
  • The wind howls, the trees dance, and the darkness wraps the night. [three independent clauses, the last two joined by the conjunction and]

NOTE: Do not confuse a compound sentence with simple sentence having a compound subject or compound verb. Remember that a compound sentence needs at least two independent clauses regardless if they have a compound subject or compound verb.
