428 Part Four • The Four Most Serious Errors
A Word That Can Cause Run-Ons: Then
Many run-ons are caused by the word then. You can use then to join two
sentences, but if you add it without the correct punctuation and/or joining
word, the resulting sentence will be a run-on. Often, writers mistakenly
use just a comma before then, but that makes a comma splice. To correct
a run-on caused by the word then, you can use any of the four methods
presented in this chapter.
COMMA SPLICE I grabbed the remote, then I ate my pizza.

CRITICAL THINKING: EDITING FOR RUN-ONS
FOCUS
• Read each sentence aloud, and listen carefully as you read.
ASK
• Am I pausing in the middle of the sentence?
• If so, are there two subjects and two verbs?
• If so, are there two complete sentences in this sentence?
• If there are two sentences (independent clauses), are they
separated by punctuation? If the answer is “no,” the sentence is a
fused sentence.
• If there is punctuation between the two independent clauses, is it
a comma only, with no coordinating conjunction? If the answer is
“yes,” the sentence is a comma splice.
EDIT
• If the sentence is a run-on, correct it using one of the four methods
for editing run-ons.
