Commas:
Use and Misuse
Comma Use
1) Commas should separate independent clauses
when preceded by one of these seven coordinating
conjunctions: for, and, nor, but, or, yet, so.
Example:
She hasn’t done her homework, but she is planning on it.
2) Commas go after introductory clauses, phrases,
or words from before the main clause.
Example:
Because he was tired from work, he fell asleep early.
To be sure, it was an exhausting day.
Unfortunatley, he was too tired to work.
3) Pairs of commas are used in the middle of a
sentence to separate clauses, phrases, and words that
are unnecessary to the meaning of the sentence.
Example:
The only day I have off from work this week, Sunday, happens to be my
mother’s birthday.
4) Commas separate three or more words, phrases,
or clauses written in a series.
Example:
He bought popcorn, candy, and soda at the movie theatre.
5) Commas separate two or more coordinate
adjectives that describe the same noun.
Example:
He is a tall, old man.
6) Commas are used at the end of sentences to
separate contrasted coordinate elements or to
indicate a pause.
Example:
It’s your birthday, right?
7) Use a comma to shift between the main
discourse and a quotation.
Example:
Harry flew into the air and said, “Give it here, Malfoy.”
Comma Misuse
1) Separating a verb from its subject.
Example:
Incorrect- The most important thing a friend can do, is support you.
Correct- The most important thing a friend can do is support you.
2) Using a comma before “that.”
Example:
Incorrect- Her dress was a similar color, that her sister wore last year.
Correct- Her dress was a similar color to the one her sister wore last year.
3) Separating verbs
Example:
Incorrect- He ran for an hour and, lifted weights for another.
Correct- He ran for an hour and lifted weights for another.
4) Comma splices (using a comma to connect two
independent clauses without a coordinating conjunction)
Example:
Incorrect- I cannot wait for summer, it is going to be so fun.
Correct- I cannot wait for summer; it is going to be so fun.
I cannot wait for summer, because it is going to be so fun.
I cannot wait for summer. It is going to be so fun.
