Commas, Restrictive Clauses and Appositives

THE COMMA (,)

            The comma is used to signal a pause or a partial stop in a sentence.  There are five grammatical situations where commas are required.

To separate a series of adjectives: 

bullet

The big, strong, handsome man…

bullet

The pretty, gentle, dark haired lady…

bullet

The fast, red, 1998 Honda…

 To separate a series of adverbs:

bullet

The old man moved slowly, deliberately painfully…

To separate an appositive:

bullet

Gigi, my wife, visited her family in Ozamiz.

bullet

My brother, who has a broken arm, won the lottery.

bullet

Our youth group, which opposes abortion, wrote a letter to the doctor

To separate a dependent clause from an independent clause when the dependent clause comes before the dependent clause:  Note: use a comma only when the DC precedes the IC.  If the DC follows the IC, no comma is needed and one should not be used.  See the examples.

bullet

Although I can, I won’t.

bullet

I wont although I can.

To separate words in a list.

bullet

 We purchased bread, milk, noodles, eggs and soap at the market.

bullet

In the basement we found old furniture, worn-out clothes, broken toys, several picture albums.

RESTRICTIVE CLAUSES AND APPOSITIVES

It is interesting to note that some sentences  may contain clauses that could be either restrictive or non-restrictive depending on the context. For example: My cousin who has a broken leg was at the picnic.  If the phrase who has a broken leg is important to your meaning, don’t use commas and say My cousin who has a broken leg was at the picnic.  If the phrase who has a broken leg is incidental, or extra information, use commas and say My cousin, who has a broken leg, was at the picnic.

IMPORTANT TIP:

To help decide whether a clause is restrictive or nonrestrictive, think of pairs of commas as handles. If you can lift out the information between the commas and the sentence still makes sense, then it is a nonrestrictive clause, and the commas are necessary. If you lift out the information and the meaning of the main clause changes, the information is a restrictive clause, and no commas are needed.
