Final answer:
A comma splice occurs when two independent clauses are joined only by a comma without a coordinating conjunction. To fix this issue, use a period, semicolon, or a coordinating conjunction (FANBOYS). Avoiding comma splices results in clearer, more structurally sound writing.
Step-by-step explanation:
A comma splice occurs when two independent clauses are joined by just a comma without the use of a coordinating conjunction. This is a grammatical error that can make your writing less clear and professional. To avoid a comma splice, you can use several methods: adding a period and making two separate sentences, inserting a semicolon, or using a coordinating conjunction such as for, and, nor, but, or, yet, or so (often remembered by the acronym FANBOYS). Another solution is subordinating one of the clauses to make a complex sentence. Incorrect use of commas can lead to run-on sentences or choppy and unclear writing.
It's important to note that not all instances of multiple independent clauses within a sentence are erroneous. They can be correctly joined using a comma with a coordinating conjunction (a compound sentence) or with one or more dependent clauses (a complex sentence).
