Combining Sentences and Clauses Coordinating Conjunctions Coordinating conjunctions are used with commas to connect two independent clauses (complete sentences with a subject and a verb). Remember FANBOYS: For, And, Nor, But, Or, Yet, So. The sentence pattern is IC, cc IC. The goat ate my hat, and the horse ate my Cheerios. Subordinating Conjunctions Subordinating conjunctions join an independent clause to a dependent clause. DC, IC. Because the goat ate my hat, my head was sunburned. IC DC. The horse ate my Cheerios because I left them in the barn.

The sentence pattern is IC; ca, IC. My team lost; consequently, it dropped in the rankings. (common examples) Accordingly Finally Likewise Specifically Also Furthermore Meanwhile Still Anyway Hence Moreover Then Besides However Nevertheless Thereafter Certainly Incidentally Now Therefore Consequently Indeed Otherwise Thereafter Conversely Instead Similarly Thus Undoubtedly Prepositions A preposition comes before a noun to create a phrase that modifies another word in the sentence. I threw a wrench into the works. A prepositional phrase at the beginning of a sentence generally ends in a comma: Below the waterline, barnacles were building a city on the keel of my boat. Prepositions inside or at the end of an independent clause do not require commas, as in the sentence above.
