Without conjunctions, you’d be forced to express every complex idea in a series of short, simplistic sentences: I like cooking. I like eating. I don’t like washing dishes afterward.What Are Conjunctions?Conjunctions are words that link other words, phrases, or clauses together.I like cooking and eating, but I don’t like washing dishes afterward. Sophie is clearly exhausted, yet she insists on dancing till dawn.Conjunctions allow you to form complex, elegant sentences and avoid the choppiness of multiple short sentences. Make sure that the phrases joined by conjunctions are parallel (share the same structure).I work quickly and careful.I work quickly and carefully.

Coordinating ConjunctionsCoordinating conjunctions allow you to join words, phrases, and clauses of equal grammatical rank in a sentence. The most common coordinating conjunctions are for, and, nor, but, or, yet, and so; you can remember them by using the mnemonic device FANBOYS.I’d like pizza or a salad for lunch. We needed a place to concentrate, so we packed up our things and went to the library. Jesse didn’t have much money, but she got by.Notice the use of the comma when a coordinating conjunction is joining two independent clauses.Correlative ConjunctionsCorrelative conjunctions are pairs of conjunctions that work together. Some examples are either/or, neither/nor, and not only/but also.Not only am I finished studying for English, but I’m also finished writing my history essay. I am finished with both my English essay and my history essay.Subordinating ConjunctionsSubordinating conjunctions join independent and dependent clauses. A subordinating conjunction can signal a cause-and-effect relationship, a contrast, or some other kind of relationship between the clauses. Common subordinating conjunctions are because, since, as, although, though, while, and whereas. Sometimes an adverb, such as until, after, or before can function as a conjunction.I can stay out until the clock strikes twelve.Here, the adverb until functions as a coordinating conjunction to connect two ideas: I can stay out (the independent clause) and the clock strikes twelve (the dependent clause). The independent clause could stand alone as a sentence; the dependent clause depends on the independent clause to make sense.The subordinating conjunction doesn’t need to go in the middle of the sentence. It has to be part of the dependent clause, but the dependent clause can come before the independent clause.Before he leaves, make sure his room is clean.If the dependent clause comes first, use a comma before the independent clause.I drank a glass of water because I was thirsty. Because I was thirsty, I drank a glass of water.
