A comma splice occurs when two independent clauses are joined together with just a comma, without a coordinating conjunction. For example, in the sentence "I love to read, I have many books," the two complete thoughts are improperly connected. This can lead to confusion for readers, as it blurs the boundaries between separate ideas. To correct a comma splice, you can use a period, a semicolon, or add a coordinating conjunction like and, but, or or. For instance, changing the previous example to "I love to read. I have many books" or "I love to read, and I have many books" resolves the issue.
