A common weakness in writing is the lack of varied sentences. Being aware of three general types of sentences (simple, compound, and complex) can help you use variety in the sentences in your writing.
The most effective writing uses a variety of sentence types explained below:
A. SIMPLE SENTENCES: A simple sentence has the most basic elements that make it a sentence: a subject, a verb, and a complement. 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.
1. Joe waited for the train.
"Joe" = subject, "waited" = verb
2. The train was late.
"The train" = subject, "was" = verb
3. Mary and Samantha took the bus.
"Mary and Samantha" = compound subject, "took" = verb
B. 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":
1. Joe waited for the train, but the train was late.
2. I looked for Mary and Samantha at the bus station, but they arrived at the station before noon and left on the bus before I arrived.
3. Mary and Samantha arrived at the bus station before noon, and they left on the bus before I arrived
C. 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:
- Because Mary and Samantha arrived at the bus station before noon
- While he waited at the train station
- After they left on the bus
Dependent clauses such as those above cannot stand alone as a sentence, but they can be added to an independent clause to form a complex sentence.
Dependent clauses begin with subordinating conjunctions. Below are some of the most common subordinating conjunctions:
- after
- although
- as
- because
- before
- even though
- if
- since
- though
- unless
- until
- when
- whenever
- whereas
- wherever
- while
