#1 Simple Sentence John drank a Pepsi. Alfred bought a diamond ring for his lovely wife Anne. Both of the sentences are simple sentences because they each only have one clause. The second may have more adjectives and adverbs, but it is still a simple sentence. #2 Compound Sentence A compound sentence uses one of the seven coordinating conjunctions (and, but, or, for, nor, so, yet) and connects two complete simple sentences. Each half of the sentence is equally important to the meaning of the sentence. The coordinating conjunction must be preceded by a comma. The seven coordinating conjunctions are also known as FANBOYS words. If these words are written out, the first letter of each one spells FANBOYS. For And Nor But Or Yet So John drank a Pepsi, and he enjoyed it. This is a compound sentence because it has a complete sentence on both sides of the coordinating conjunction, the sentences make sense together, and the coordinating conjunction makes sense with the sentences. John drank a Pepsi, or he enjoyed it. John drank a Pepsi, nor he enjoyed it. These are examples of faulty coordination since the coordinating conjunction does not make sense with the sentences it is connecting. John drank a Pepsi, so computers hate people who have poor usage skills. This is another example of faulty coordination because these two sentences don’t make any logical sense together. #3 Complex Sentence Complex sentences consist of a subordinate clause and an independent clause. The independent clause is the important part of the sentence. The subordinate clause is only additional information. A comma separates the subordinate clause from the independent clause when the subordinate clause precedes the independent clause. HUH??? Clauses can provide more information in a sentence.

Dependent clauses are created by placing either a subordinating word or a relative pronoun in front of a sentence. Common subordinating words include: as because If after since provided before where unless whether whileonce when although so that until though whenever than as if Common relative pronouns include: which what who that whom whatever whoever Because John drank a Pepsi. This is a subordinate clause because it doesn’t express a complete thought and must rely upon an independent clause to give it meaning. Because John drank a Pepsi, what happened? subordinate clause independent clause Because John drank a Pepsi, he was no longer thirsty. When the dependent clause comes first, separate the clauses with a comma. Independent clause subordinate clause He was no longer thirsty because John drank a Pepsi. When the independent clause comes first, no comma is necessary.
