Grammar Explanation

•  A run-on is a sentence that contains two independent clauses without punctuation between them. To fix a run-on, use a period or semi-colon to separate the clauses into two sentences or combine the clauses using a conjunction preceded by a comma.
  • Example of run-on: Over the past few decades, the number of female prisoners has been growing at a faster pace than the number of male prisoners there are more than 100,000 female inmates in the nation's prisons and jails today.
  • Corrected version: Over the past few decades, the number of female prisoners has been growing at a faster pace than the number of male prisoners; there are more than 100,000 female inmates in the nation's prisons and jails today.
•  The most common type of run-on sentence is called a comma splice. It occurs when a comma is used between two independent clauses without a coordinating conjunction.
  • Example of comma splice: The majority of prison inmates have both emotional and social problems, prison officials have begun to employ modern counseling methods to help inmates address these problems.
  • Corrected version: The majority of prison inmates have both emotional and social problems, so prison officials have begun to employ modern counseling methods to help inmates address these problems.
