What is a run-on or fused sentence or comma splice?

Answer 1

These are all sentences made up of independent clauses that are not joined by a coordinating conjunction or correct punctuation.

A comma splice is a sentence with two independent clauses joined only by a comma: Answer every question to the best of your ability, however, do not spend too much time on any one question.

This can be corrected in two ways;

1. Separate it into two sentences: Answer every question to the best of your ability. However, do not spend too much time on any one question.

2. Use a semicolon instead of the comma: Answer every question to the best of your ability; however, do not spend too much time on any one question.

A run-on or fused sentence is made up of independent clauses with no coordinating conjunction and no punctuation between them: Extremely hot weather can be dangerous drink plenty of water. One way to correct this is to insert a coordinating conjunction: Extremely hot weather can be dangerous, so dring plenty of water.

Answer 2

A run-on sentence occurs when two or more independent clauses are joined without proper punctuation. A fused sentence, also known as a comma splice, happens when two independent clauses are incorrectly joined with a comma alone. Both errors result in a lack of proper separation between distinct ideas.
