LESSON 16: COMPOUND SENTENCES Relevant Review • •
Coordinating Conjunctions = for, and, nor, but, or, yet, so Do you remember how to diagram compound prepositions, verb phrases, adjectives, adverbs, subjects, verbs, and direct objects? (If not, review lessons 13-15.)
Lesson Now it's time to diagram compound sentences. That means you’ll be diagramming two or more independent clauses* joined by a coordinating conjunction. * A clause is a group of words that contains a subject and a verb. There are two main types of clauses: independent and dependent. Independent clauses express complete thoughts and can stand all alone as complete ideas. They are basically sentences, which is what we have been studying all along. We’ll learn more about clauses starting in lesson 26. Here are some examples of compound sentences. I’ll give you one example for each coordinating conjunction. Coordinating Conjunction for
Compound Sentence I felt sleepy, for I had not slept in days.
and
I ate chicken for dinner, and Joe ate pizza.
nor
I did not want to sleep, nor did I want to rest.
but
I want to play at the park, but my brother wants to play at home.
or
Dad can pick you up, or you can take the bus.
yet
I was tired, yet I was happy.
so
It was dinner time, so I cooked a fabulous meal.
Did you notice that each example is just one sentence, but each sentence contains two independent clauses? There is an independent clause on either side of each coordinating conjunction.

Diagramming Compound Sentences You’re going to love how easy it is to diagram compound sentences. Diagram one independent clause on top of the other and place the conjunction on a dotted vertical line connecting the two diagrams on the left side. I ate chicken for dinner, and Joe ate pizza. Notice that the first independent clause is I ate chicken for dinner. Start by diagramming that first clause. The next clause is Joe ate pizza. Again, this is an independent clause that can stand all alone as a complete idea. Diagram it below the first clause. Finally, connect the two diagrams with a dotted vertical line. Place the coordinating conjunction on that line.
If the conjunction joins more than two independent clauses, stack all of the clauses on top of each other and connect them with the coordinating conjunction.
