What is a “run-on” sentence?
Run-on sentences, also known as "fused sentences," contain two independent clauses incorrectly joined (Hacker 200). While a sentence fragment is an incomplete sentence, a run-on jams together two or more sentences without the correct punctuation (Faigley 579).
Run-on sentences come in two types: the comma splice and the fused sentence. When two independent clauses are connected by a comma, this run-on is called a comma splice (Hult 721).
- Comma splice: I purchased most of what I needed at the store, they were out of milk.
When there is no comma, the run-on sentence is fused (Hacker 200).
- Fused: I purchased most of what I needed at the store they were out of milk.
A run-on can be a short sentence, such as, "Nothing is on television I should turn it off." Just because a sentence is long, though, does not necessarily make it a run-on.
The Rules
To avoid a run-on sentence:
- Separate the clauses with a semicolon — or a colon or dash, when appropriate (Hacker 202).
- Insert a comma and a coordinating conjunction between the clauses (Faigley 581).
- Turn one clause into a subordinating clause (Hult 722).
- Make the clauses into seperate sentences (Hacker 202).
Usage
Semicolon
If the clauses are equally important, use a semicolon to separate them (Hult 723).
- I purchased most of what I needed at the store; they were out of milk.
A transitional word might also help the sentence flow and clarity (Faigley 581):
- I purchased most of what I needed at the store; however, they were out of milk.
