Punctuation Patterns for Several Sentence Types

Definitions

  • A clause is a group of words with a subject and a verb. It is used as a sentence or as part of a sentence.

  • An independent clause can stand alone. It makes complete sense by itself.

    Example: Tom Smith was late.

  • A dependent clause cannot stand alone. It must be attached to an independent clause in order to make a complete sentence.

    Example: because his car broke down
  • A conjunctive adverb is used to connected clauses, dependent and independent.

    Examples: therefore, moreover, however, furthermore, etc.

  • A coordinating conjuction

    Examples: and, but, for, or, nor, so, yet, etc.

  • A subordinating conjuction

    Examples: after, because, when, if, while, where, as, unless, since, etc.
