Unbreakable Grammar Rule #1: The Comma Splice

What is a Comma Splice?

A comma splice is the use of a comma to join two independent clauses. For example:
It is nearly half past five, we cannot reach town before dark.

How to Fix a Comma Splice

1. Change the comma to a semicolon, dash, or colon:

  • It is nearly half past five; we cannot reach town before dark.
  • It is nearly half past five—we cannot reach town before dark.
  • We cannot reach town before dark: it is nearly half past five.

2. Write the two clauses as two separate sentences:

  • It is nearly half past five. We cannot reach town before dark.

3. Insert a coordinating conjunction following the comma:

  • It is nearly half past five, and we cannot reach town before dark.
  • It is nearly half past five, so we cannot reach town before dark.

4. Make one clause dependent on the other:

  • Because it is nearly half past five, we cannot reach town before dark.

5. Use a semicolon plus a conjunctive adverb:

  • It is nearly half past five; hence, we cannot reach town before dark.
