02/12/01: Comma before "and"
One of the questions we are asked frequently is whether a comma
should go before the conjunction "and" in a series of three or more items.
The answer is yes. Although grammar gurus abandoned that comma rule for
a while in the twentieth century, we have since realized that using the
serial comma (as it is called) is a good idea for two reasons:
First, it prevents misreading. Consider this sentence, for example:
The menu for the class picnic will feature green beans, stewed apples,
macaroni and cheese and okra and tomatoes.
Without the serial comma, the series items are difficult to see. Here
is the same sentence with the serial comma added:
The menu for the class picnic will feature green beans, stewed apples,
macaroni and cheese, and okra and tomatoes.
With the serial comma, the reader can tell easily that the class ate
four different dishes, not five or six, as may have been construed without
that last comma.
The Texas Law Review Manual on Usage and Style, considered highly authoritative
in legal circles, insists on the use of serial commas, as do a number of
other reputable style manuals. The Lawyer’s Book of Rules for Effective
Legal Writing, by Thomas R. Haggard, says "The serial comma is essential
in legal writing because it promotes clarity" (17). Consider this
sentence:
Mrs. Jones left all her money to her three children: Huey, Dewey and
Louie.
Without the serial comma, the sentence does not clearly indicate that
the three children are to be given equal shares of the inheritance. Quite
possibly (especially if Huey were a jerk), Huey would get half the money,
and Dewey and Louie would have to split the other half. Here’s another example:
Mrs. Jones left her money to Sally and Fred Smith, Margaret and John
Williams, Betty and Harold Spivey and their children.
Without the serial comma, the sentence could be interpreted to mean
that only Betty and Harold Spivey’s children would receive a share of the
inheritance. With the comma, the sentence would clearly communicate
that the children of all three couples were to receive a share:
Mrs. Jones left her money to Sally and Fred Smith, Margaret and John
Williams, Betty and Harold Spivey, and their children.
Many times the comma may seem unnecessary because the writer may believe
there is no room for confusion in the sentence. If we were to write,
for example, “The table was covered with food, gifts and flowers,” the
meaning would be quite clear without the serial comma. But as writers,
we are usually poor judges of our own writing and may be ill suited to
judge its clarity, so play it safe and use the serial comma every time.
Keep in mind, of course, that a comma is incorrect when the word “and”
joins only two equal, or coordinate, elements in a sentence (e.g., two
subjects of the same verb, two verbs that have the same subject, two direct
objects of the same verb, two objects of the same preposition, two paired
phrases), as in these examples:
Mrs. Jones left her money to Sally and Fred.
We were entertained by the musicians’ performance and by the conductor’s
