There are four types of sentences, and in the interest of varying sentence structure students should learn how to convert from one sentence type to another. This can be confusing but using a complex sentence maker will simplify the task.

Simple, Compound and Complex Sentences

Of the four sentence types the ones you will encounter most often are the simple sentence, the compound sentence and the complex sentence.

  • Simple sentence. A simple sentence as the name suggests is a sentence in its most basic form. It is a single independent clause with a subject and a predicate. It will consist of a subject and verb (SV) or a subject, a verb and an object (SVO).
    • Example: James kicked the ball.
  • Compound sentence. A compound sentence is made up of at least two independent clauses that contain related ideas. The independent clauses may be joined by a conjunction (for, and, nor, but, or, yet, so) or by a semicolon.
    • Example: My friends were all busy, so I went to the movie alone.
    • Example: My friends were all busy; I went to the movie alone.
  • Complex sentence. A complex sentence has an independent clause and one or more dependents clauses. Unlike the independent clause, a dependent clause can’t stand on its own as a sentence. If the independent clause comes first in the sentence the independent and dependent clause requires subordinating conjunction (after, while, since, etc.) to join them. If the dependent clause comes first the two clauses can be joined by a comma.
    • Example: Bill returned the computer after he noticed it was damaged.
    • Example: Because he noticed it was damaged, Bill returned the computer.

Editing Strategies for Checking Simple and Complex Sentences

The following are some techniques and approaches you can use when editing simple and complex sentences.

how to change a simple sentence to a compound, complex sentence
  • Learn the difference between an independent clause and a dependent (subordinate) clause. Independent clauses can stand alone as a complete sentence. Dependent clauses can’t.
  • Memorize the 7 conjunctions (for, and, nor, but, or, yet, so) for joining two independent clauses. You can easily remember them using the acronym FANBOYS.
  • Check if the dependent clause in the complex sentence comes before or after the independent clause. If the dependent clause is first the two clauses can be joined by a comma. When the dependent clause follows the independent clause a subordinating conjunction must be used.
  • Become familiar with the three types of subordinate clauses. The adjective clause modifies a noun or pronoun, the adverb clause modifies a verb, an adjective or another adverb and a noun clause is used as a noun in independent clauses
  • Mix up your sentences. Don’t just use only simple sentences or only complex sentences. Use a combination of simple, complex and compound sentences when you write
  • Read sentences out loud. It is often easier to detect mistakes when you hear them spoken than when you see them on paper or your computer screen.

If you are unfamiliar with all the different sentence parts and need help with sentence structure try using a sentence breakdown tool such as the one we offer.
