Summary: Run-on sentences

print page print

Run-on sentences are grammatical errors. They happen when you join two simple sentences without using either a co-ordinating or subordinating conjunction.

You cannot join two (or more) simple sentences using a comma only, or a comma with a connector that is not a co-ordinating or subordinating conjunction. Either use:

  • a co-ordinating or subordinating conjunction;
  • a co-ordinating or subordinating conjunction plus the other connecting word; or
  • leave them as two separate sentences.

Avoid exclamations and commands altogether in academic writing, and think twice about using questions.
