Compound Sentences

Independent Clauses

A simple sentence can also be called an independent clause. An independent clause is a subject and verb that is a complete idea. It does not need more information to complete the thought.

You can connect separate independent clauses (simple sentences) using a coordinating conjunction. Coordinating conjunctions are words that connect the two sentences together. You use them when the ideas in the sentences are connected.

• I have a dog, and I want another dog.

See that both sentences are complete. You can separate them with a period. However, the meaning of the sentences is connected, so you can use a coordinating conjunction to make the connection clear. When a sentence has more than one independent clause, it is called a compound sentence.

Coordinating Conjunctions

Coordinating conjunctions in English are for, and, nor, but, or, yet, and so. We often use the word FANBOYS to remember these words. When you use a coordinating conjunction (FANBOYS), you will use a comma before the second independent clause.

• F – Bring an umbrella, for it will rain this afternoon.
  • This word shows a cause or reason connection.
  • This is more formal and not common.
• A – Reading class is first, and writing class is second.
  • This word shows addition, time order, or cause/reason.
• N – I never liked broccoli, nor will I ever like it.
  • This shows that both clauses are not true or do not happen.
  • This is use more in formal English.
• B – Rei was late to class, but he did participate.
  • This shows a difference connection.
• O – My classmates are going to karaoke, or they are going bowling.
  • This word shows a choice between the clauses.
