commas
2
  • Rule 1
  • Commas need to accompany conjunctions in compound
    sentences.
  • They are used to separate two independent clauses
    joined by a conjunction.
  • The market is full of exotic produce, and the
    prices are being driven up.
  • I smiled, but I feared she was right.
  • He forgot to call his girlfriend
  • yesterday, so he called her today.

3
Where not to put a comma...
  • Do not separate compound subjects and/or
    compound verbs with a comma
  • incorrect - Tom, and Jerry went to the basketball
    game.
  • correct - Tom and Jerry went to the basketball
    game.
  • incorrect - Sally ran, and jumped down the path.
  • correct - Sally ran and jumped down the path.

4
  • REMEMBER . . .
  • A comma alone will result in a comma splice
  • incorrect - I didnt believe a word Phil said, I
    told him so.
  • correct - I didnt believe a word Phil said, and
    I told him so.

5
Rule 2Use a comma to set off an introductory
subordinate clause.
When the riot started, the police fired tear gas
into the crowd.Because the 1993 flood was so
devastating, some farmers in the Mid-west decided
to relocate.
6
Rule 3Do not put a comma after the main
clause when a dependent (subordinate) clause
follows it (except for cases of extreme
contrast).
She was still quite upset, although she had won
the Oscar.
Some people refused to leave their homes, even
though the hurricane winds had started.
7
  • NOTE that in the following sentences the idea in
    the main clause will not be realized without the
    subordinate clause therefore, we use no comma
  • Ill pack up and leave if you tell me to.
  • We left the area because we were afraid to stay.
  •  
  • In general, if and because clauses are NOT set
    off those introduced by although and even though
    are. If you are in doubt about the punctuation of
    the clause in post-sentence position, you can
    shift it to to the beginning of the sentence
    there it will always be set off.

8
Rule 4Use a comma to set off any introductory
phrase that contains a verb form.
  • After studying all weekend, I felt absolutely
    prepared for the mid-term exam.
  • Having worked at McDonalds for the past four
    summers, Max felt confident when he applied for
    the job of assistant manager.
  • To get in shape for ski season, my roommate has
    begun working out on the Nordic Track.

9
use commas after introductory a) clauses b)
phrases c) words that come before the main
clause
Basically...
  • While I was eating, the cat scratched at the
    door.
  • Because her alarm clock was broken, she was late
    for class.
  • If you are ill, you ought to see a doctor.When
    the snow stops falling, we'll shovel the
    driveway.

10
Rule 5 Use a comma to set off adverbial
prepositional phrases of approximately six or
more words.
  • Towards the end of the semester, everyone in my
    dorm starts to study seriously.
  • It is perfectly acceptable to set off shorter
    prepositional phrases, especially if you think
    the reader should pause. For example, information
    of specific dates is sometimes set off
  • In 1994, Republicans gained strength in the
    midterm election.
  •  

11
In making decisions about such commas, consider
the punctuation in the rest of the sentence
Dont overload the sentence with commas. Also,
set off any prepositional phrase that might cause
a misreading
During the summer, vacation plans are our main
topic of conversation.
12
Rule 6Set off words and phrases that modify
the whole sentence or that have a parenthetical
meaningat both the beginning and the end of the
sentence.
  • Adverbs
  • Luckily, we escaped without a scratch.
  • We escaped without a scratch, luckily.
  • Meanwhile, there was nothing to do but wait.

13
Yes and No Sentences beginning with yes or
no, need a comma after yes or no.Yes, hes
the culprit. No, I cant go out
tonight.
Absolute phrasesAbsolute phrases A group of
words that modifies an independent clause as a
whole and does not contain a conjunction. The
rain having stopped, Doug and Deborah decided to
go ahead with the picnic.Eben and Paula relaxed
in front of the fire, their feet propped on the
coffee table.
14
Rule 7 Use commas to set off commenting
(nonrestrictive) modifiers in the noun phrase.
  • My oldest brother, who is a senior history major,
    spends every night in the library.
  • If the clause restricts the meaning of the
    sentence, then do NOT put commas before or after
    the clause
  • The woman who wore the neon pink dress at the
    party forgot her purse.

15
  • Rule 8Use commas to separate two or more
    coordinate adjectives that describe the same
    noun. Be sure never to add an extra comma between
    the final adjective and the noun itself or to use
    commas with non-coordinate adjectives.

Coordinate adjectives are adjectives with equal
("co"-ordinate) status in describing the noun.
16
  • Coordinate refers to adjectives of the same
    classfor example, subjective qualities.
  • a tender, delightful love story
  • a challenging, educational experience
  • a tall young man
  • a huge red ball
  • A good rule of thumb for making a decision
    about commas between these prenoun modifiers is
    this If you could insert and or but, use a
    comma
  • a tender and delightful love story
  • Notice that the two phrases without commas (a
    tall young man AND a huge red ball) contain
    adjectives from different classes (height, age,
    size, color)so they will not be separated.

17
Rule 9Use a comma to set off nouns of direct
address in both opening and closing position.
  • Students, your time is up.
  • Put your pencils down, everyone.
  • Help me, dear!

18
Rule 10Use commas to set off direct
quotations that fill the direct object slot after
verbs such as say and reply.
  • The waiter said, Good evening. My name is
    Pierre.
  • Im Harold, and this is Joyce, Harold replied.

19
Rule 11Use commas to set off the name of a
state when it follows the name of a city and to
set off the year in a complete date.
  • I was surprised to learn that Cheyenne, Wyoming,
    isnt a larger city.
  • I remember where I was on November 22, 1963, when
    I heard the news reports of President Kennedys
    assassination.
