Run-on Sentences
Run-on sentences (or fused sentences) express more than one complete thought without
proper punctuation. Run-ons can be repaired by setting ideas apart with end punctuation or by
joining the ideas with a comma, or they may be linked using a semicolon; however, there are a
few rules to remember when using each of these punctuation marks:
A comma which separates two independent clauses is followed by a coordinating conjunction (a
FANBOY).
Tom is a full-time English student, and he works part-time as well.
His sister is an accountant, so she is better at math than he is.
Semi-colons join independent clauses without the help of a FANBOY; however, a conjunctive
adverb may be added in order to express a particular relationship between clauses.
It is cold outside; I should probably wear a jacket.
Jill is a very busy person; consequently, she has little time to socialize.
No comma is used if an independent clause is written before one which is dependent upon it, but
if the dependent clause comes first a comma should be used.
You can come to the store with us if you want to. (no comma is needed)
If you need some extra help, you should come to the Writing Resource Center.
