Comma Splices and Run-on Sentences

(see LBB, chapter 36, pages 332-339)

 

Comma Splice: joining two sentences together with only a comma

 

Run-on Sentence: joining two sentences together without any punctuation

 

To fix a CS or an RO:

 

1.) Separate the two sentences with a period ( . )

 

2.) Separate the two sentences with a semicolon ( ; )

 

3.) Use a semicolon ( ; ) + a conjunctive adverb (however, therefore, nevertheless, furthermore, etc.)

 

4.) Use a comma ( , ) + a coordinating conjunction (and, but, or, nor, for, so, yet)

 

5.) Turn one sentence into a dependent clause using a subordinating conjunction (although, because, before, if, since, unless, when, while, etc.) or a relative pronoun (which, that, who, etc.)

 

6.) In certain cases, you might use a colon ( : ) -- the colon is used at the end of one sentence to "introduce" the next sentence, which is often, but not always, a quotation.
