Sentences: Simple, Compound, and Complex
A common weakness in writing is the lack of varied sentences. Becoming aware of three general types of sentences--simple, compound, and complex--can help you vary the sentences in your writing. The most effective writing uses a variety of the sentence types explained below. 1. Simple Sentences A simple sentence has the most basic elements that make it a sentence: a subject, a verb, and a completed thought. Examples of simple sentences include the following: Tip: If you use many simple sentences in an essay, you should consider revising some of the sentences into compound or complex sentences (explained below). The use of compound subjects, compound verbs, prepositional phrases (such as "at the bus station"), and other elements help lengthen simple sentences, but simple sentences often are short. The use of too many simple sentences can make writing "choppy" and can prevent the writing from flowing smoothly. A simple sentence can also be referred to as an independent clause. It is referred to as "independent" because, while it might be part of a compound or complex sentence, it can also stand by itself as a complete sentence. 2. Compound Sentences A compound sentence refers to a sentence made up of two independent clauses (or complete sentences) connected to one another with a coordinating conjunction. Coordinating conjunctions are easy to remember if you think of the words "FAN BOYS":

Clearer and more specific relationships can be established through
the use of complex sentences. 3. Complex Sentences A complex sentence is made up of an independent clause and one or more dependent clauses connected to it. A dependent clause is similar to an independent clause, or complete sentence, but it lacks one of the elements that would make it a complete sentence. Examples of dependent clauses include the following:
Dependent clauses begin with subordinating conjunctions. Below are some of the most common subordinating conjunctions:
The dependent clauses can go first in the sentence, followed by the independent clause, as in the following: Tip: When the dependent clause comes first, a comma should be used to separate the two clauses.
Tip: When the independent clause comes first, a comma should not be used to separate the two clauses.
The term periodic sentence is used to refer to a complex sentence beginning with a dependent clause and ending with an independent clause, as in "While he waited at the train station, Joe realized that the train was late." Periodic sentences can be especially effective because the completed thought occurs at the end of it, so the first part of the sentence can build up to the meaning that comes at the end. |
Should you begin a sentence with "and" or "but" (or one of the other coordinating conjunctions)?
The short answer is "no." You should avoid beginning a sentence with "and," "or," "but," or the other coordinating conjunctions. These words generally are used to join together parts of a sentence, not to begin a new sentence.
However, such sentences can be used effectively. Because sentences beginning with these words stand out, they are sometimes used for emphasis. If you use sentences beginning with one of the coordinating conjunctions, you should use these sentences sparingly and carefully.
Should you begin a sentence with "because"?
There is nothing wrong with beginning a sentence with "because."
Perhaps some students are told not to begin a sentence with "because" to avoid sentence fragments (something like "Because Mary and Samantha arrived at the bus station before noon" is a sentence fragment), but it is perfectly acceptable to begin a sentence with "because" as long as the sentence is complete (as in "Because Mary and Samantha arrived at the bus station before noon, I did not see them at the station.")
