Sentence Structure Notes

Sentence Requirements:

In order for a sentence to be complete, it must contain three key components.

  • It must contain a subject
  • It must contain a predicate
  • It must express a complete thought

SUBJECT – the subject in the sentence is who or what the sentence is about.

  • The boy ran down the street. (subject is “the boy”)

PREDICATE – the predicate is what is happening to the subject.

  • The boy ran down the street. (predicate is “ran down the street”)

CLAUSES

Sentences are made up of clauses. There are two types of clauses.

  • Independent Clause – contains a subject, predicate, and expresses complete thought. An independent clause can stand alone as a sentence. Some sentences have more than one clause.
  • The boy ran down the street. (1 clause)
  • Jimmy went to the store to buy milk, and he stopped by the video store on the way home. (2 clauses)
  • Dependent Clause – contains a subject and predicate, but it does not express a complete thought. Dependent clauses need an independent clause in order to complete a sentence.
  • Whenever I go to the mall (this is a dependent clause therefore it is not a complete sentence. It needs help from an independent clause)
  • Whenever I go to the mall, I stop at Jugo Juice for a drink. (1 dependent clause supported by an independent clause)

TYPES OF SENTENCES

There are three basic types of sentences:

  • Simple Sentence – contains one independent clause.
  • The boy ran down the street.
  • Compound Sentence – contains two independent clauses joined by a conjunction (and, but, so)
  • The boy ran down the street, so he could catch the ice cream truck.
  • Complex Sentence – contains one independent and one dependent clause.
  • Whenever the boy hears the ice cream truck, he runs frantically after it.

STYLES OF SENTENCES

There are four different styles of sentences.

  • Declarative – makes a statement
  • Imperative – gives a command
  • Interrogative - asks a question
  • Exclamatory – shows strong emotion or surprise (ends with “!”)
