COMMA SPLICE: the connecting of two complete sentences (independent clauses) with only a comma.

ex.  James drove his car very fast, he never got a speeding ticket.

        1.  Use a period in place of the comma to create two independent sentences.

             James drove his car very fast.  He never got a speeding ticket.

        2.  Use a coordinating conjunction (and, or, nor, yet, but, so, for) after the comma.

             James drove his car very fast, but he never got a speeding ticket.

        3.  Use a semicolon if the sentences are closely related.

             James drove his car very fast;  he never got a speeding ticket.

RUN-ON or FUSED SENTENCES: the connecting of two complete sentences (independent clauses) without using punctuation.

ex.  James drove his car very fast he never got a speeding ticket.


SENTENCE FRAGMENT: an incomplete sentence.

ex.  Came home from the store.

            I came home from the store. Fragment:   When I came home from the store.

Corrected:  I put the groceries away when I came home from the store.
                    When I came home from the store, I put the groceries away.

NOUN/PRONOUN AGREEMENT:  the form of the noun and the pronoun must be equal in number/ person/ gender.

ex. A person needs to see their doctor yearly.


            A person needs to see her (his) doctor yearly.
            People need to see their doctor yearly.
            Mary gave her bicycle away.
            The school changed its mind about the hiring policy.

SUBJECT/VERB AGREEMENT:  the subject and the verb must agree in number.

            John Ciardi wrote, "There were anger and hatred in that voice."

ACTIVE VOICE:  the subject of the sentence performs the action of the verb and the direct object receives the action of verb.

            Shakespeare wrote Hamlet. [SUBJECT+ VERB+ DIRECT OBJECT]

PASSIVE VOICE: the direct object becomes the subject of the sentence and a passive verb [ verb phrase of a form of the verb to be] is used.

            Hamlet was written by Shakespeare.  [DIRECT OBJECT AS SUBJECT+ PASSIVE VERB FORM]

Note:  When writing an essay or any type of classroom assignment, you should use the active voice to gain emphasis.  You can use the passive voice when the receiver of the action is more important than the performer of the action.

            During a high speed chase, the police car struck an innocent pedestrian. [active voice]
            During a high speed chase, an innocent pedestrian was struck by the police car. [passive voice]
