Final answer:
Run-on sentences occur when independent clauses are improperly joined or when a comma is used incorrectly. The two types are comma splice and fused sentences.
Step-by-step explanation:
Definition of Run-on Sentences
Run-on sentences occur when two or more independent clauses are improperly joined together or when a comma is used incorrectly to separate two independent clauses. The two types of run-on sentences are comma splice and fused sentences.
Comma Splice
A comma splice is a run-on sentence that occurs when two independent clauses are joined together with only a comma. For example: 'I love to read books, I also enjoy watching movies.'
Fused Sentences
A fused sentence, also known as a run-on sentence, happens when two independent clauses are joined together without any punctuation or conjunction to separate them. For example: 'I love to read books I also enjoy watching movies.'
