Sentence Structure​

A sentence is a group of words that expresses a complete thought. It must have a subject and a verb and make sense.
There are many types of sentence structures, but the most common are simple, compound, and complex sentences.
Simple Sentences
A simple sentence has one subject and one verb. The subject is the person, place, thing, or idea of the sentence. The verb is the action that the subject is doing or being.
For example:
  • The cat is black.
  • The dog chases the ball.
  • The house is big.
Compound Sentences
A compound sentence has two or more independent clauses. An independent clause is a group of words that can stand independently as a sentence. Compound sentences are joined by coordinating conjunctions, such as and, but, or, nor, for, so, and yet.
For example:
  • The cat is black, but the dog is white.
  • The dog chases the ball, and the cat watches.
  • The house is big, yet it is not very expensive.
Complex Sentences
A complex sentence has one independent clause and one or more dependent clauses. A dependent clause is a group of words that cannot stand alone as a sentence. Dependent clauses are joined to independent clauses by subordinating conjunctions, such as after, although, as, as if, as long as, as soon as, because, before, even though, if, so that, since, so that, then, though, unless, until, when, whenever, where, and while.
For example:
  • The cat is black because it has black fur.
  • The dog chases the ball even though it knows it will never catch it.
  • The house is big because it has four bedrooms and three bathrooms.
