What is a Comma Splice

A comma splice happens when two complete sentences get incorrectly joined with only a comma, and no connecting word. When each half of a sentence can stand alone as its own, a comma isn’t strong enough to connect them.

Comma splices can show up in everyday and professional writing, especially when thoughts flow quickly. It isn't always obvious at first glance. Which is why comma splicing is easy to miss.
