A comma splice occurs when two ideas are joined together with a comma. Unless the ideas are closely related, they should be placed in separate sentences. If the ideas are closely related, then it may be possible to join the ideas with additional words or different punctuation.


Sentences that contain too many ideas are considered to be run–on sentences.

  • Incorrect:
