How do I correct my comma splices and run-on sentences?

 

 

A comma splice incorrectly joins two sentences with only a comma:

                       

He brought his draft to the Writing Center, the consultant offered good suggestions.

 

A run-on sentence is two sentences written together as though one long sentence:

 

He brought his draft to the Writing Center the consultant offered good suggestions.

 

 

There are four ways to correct comma splices and run-on sentences

 

 

 

Separate the sentences with a period:

 

He brought his draft to the Writing Center.  The consultant offered good suggestions.

 

Join the two sentences with a comma plus coordinating conjunction, such as “and” or “but”:

 

He brought his draft to the Writing Center, and the consultant offered good suggestions.

 

Make one of the sentences a partial sentence:

 

He brought his draft to the Writing Center, where the consultant offered good suggestions.

 

 

Or, join sentences with a semicolon:                                             

 

Use several drafts when writing a paper; that’s how you’ll produce your best work.

 

·        Join sentences with a semicolon only when the second sentence clarifies the first sentence.  Note that the second sentence, “that’s how you’ll produce your best work,” explains why you should use several drafts when writing a paper. 

 

A test for semicolon usage is to try the word because or so in place of the semicolon and then read the sentences.  If because or so would make sense as a substitute for the semicolon, the semicolon is probably correct.
