Comma Worksheet
The comma is the most frequent used (and abused) aid to reading. Just as pauses and variations in voice pitch
help to convey the meaning of spoken sentences, commas help to clarify the meaning of written sentences.
(Try to avoid using pausing and breathing, however, since that causes confusion. Sentence structure is a much
better way to punctuate.)

When the lightning struck James, Harvey fainted.
The sound of a sentence can serve as a guide in using commas. But many times sound is not a dependable
guide. Rules that govern comma usage may become detailed and involved unless they are presented in an
orderly manner. For this reason, consider first these five basic categories of comma usage:
1. A comma precedes the coordinating conjunction joining two independent
clauses.
2. A comma follows certain introductory elements.
3. A comma separates items in a series.
4. Nonrestrictive clauses and phrases and other parenthetical elements are
set off with commas.
5. Items in dates and addresses are set off with commas.
Area One
A COMMA PRECEDES THE COORDINATING CONJUNCTION JOINING TWO INDEPENDENT
CLAUSES.
Note the following pattern in compound sentences:
INDEPENDENT CLAUSE, (and, but, or, nor, for, yet, so) INDEPENDENT CLAUSE.
Study the use of commas in the compound sentences below.

any common cause.
No one watches the performance, for everybody is taking part.

Space can be mapped and crossed and occupied, yet it can never be conquered.
Caution: Do not confuse the compound sentence with a simple sentence containing a
compound element. This is a very common error. Study the examples below.

A comma is used to separate words, phrases, or clauses in a series. A series has three or more items. The
comma before the conjunction is often omitted when the series takes the form a, b, and c. But students are
usually advised to use the final comma because it is sometimes needed to prevent confusion.

Area Four
NONRESTRICTIVE CLAUSES AND PHRASES AND OTHER PARENTHETICAL ELEMENTS ARE SET OFF
WITH COMMAS.
Commas set off nonrestrictive clauses and phrases. Restrictive clauses and phrases are not set off. Adjective
clauses and phrases are nonrestrictive when they are not essential to the meaning of the sentence and may be
omitted. Study the following examples very carefully. Phrases and clauses are underlined.
Ben Franklin, best known for politics, was a printer. ("…best known for his politics" is simply added
information.)


The idea that appeals to me most is to go to the museum. (No commas because "that appeals to me
most" tells which idea. Adjective clauses beginning with that are always restrictive.)
Our class president, who is also the brightest student, has a pig for a pet. ( "…who is also the brightest
student" is nonessential or added information.)
The child who finishes first will receive a prize. (No commas because the adjective clause is necessary
to identify which child.)
That fascinating discussion was led by Mrs. Jackson, who employs irony with great skill and humor.
(Mrs. Jackson is identifiable by name, so the adjective clause is unnecessary to identify her. Adjective
clauses are always nonrestrictive if they modify proper names.)
The two things most universally desired are power and admiration. (No commas because the phrase is
necessary to the sense of the sentence.)
Sometimes a clause or phrase may be either nonrestrictive or restrictive. The writer signifies his meaning by
using or omitting commas. Of course, this is sometimes a hazardous approach because people do not always
understand sophisticated comma usage.
