Coordinating Conjunctions
by John Davis

Quite often sentences have two or more elements that need to be linked in order for the sentence make sense.  Any of the following coordinating conjunctions can be used to join nouns, verbs, and independent clauses:

  • And
  • But
  • Or
  • So
  • Nor
  • For
  • Yet
 

Linking Independent Clauses

Using coordinating conjunctions can become more complex when you link independent clauses.  A decision has to be made about the meaning of the sentence before the appropriate coordinating conjunction can be used. 

Here are some of the ways these conjunctions are used:

AND:      used to group similar elements together

Ex:  Steve won the gold medal for the ten-meter dash at last week’s track meet, and he also won the silver medal for the long jump at yesterday’s field tournament.

 OR:         used to denote an alternative

Ex:  The manager should communicate guidelines for employees to follow, or the workers may become confused about organizational procedures.

 BUT:       used to qualify or restrict the first independent clause.  It also can be used to contrast the first independent clause with the second or to provide an exception to the first independent clause.

Ex:  The red wire should be connected to the upper terminal of the fuse, but the red wire needs to be connected to the lower terminal if the fuse was made before 1980.

SO:         used to show cause and effect by introducing the effect

Ex:  The officer filled out her paper work quickly, so she could get home on time for dinner.

 FOR:       used to show cause and effect by introducing the cause  (less common, generally used for literary effect)

Ex:  Diane leaves her house an hour early, for the traffic is too heavy at rush hour to get to work on time.

NOR:      used to continue a negative (typically seen as “…neither…nor…”)

Ex:  The additional act in the play was neither part of the original manuscript, nor did the writer approve of its inclusion. 

Notice the inverted word order of the second independent clause.

YET:       used to show a discrepancy being discussed by the two clauses. Like but, yet can show contrast or contradiction.

Ex:  Cigarette companies maintain that they did not know about the harmful effects of tobacco, yet the memos discovered in their offices proved that the companies were aware that smoking causes lung cancer.

TIP:
The idea that sentences should not be started by coordinating conjunctions, such as and or or, is a myth that is sometimes taught in both high school and junior high school.  The way to keep the sentence structure correct is to be sure that the preceding sentence logically allows the second sentence to use a coordinating conjunction as its first word.

                                                Definitions

Coordinating conjunctions—and, or, but, nor, for, so, yet—join words, phrases and clauses of equal grammatical rank.  (Prentice Hall Handbook for Writers)

Clause: A clause is a group of related words that contains a subject and a predicate.  A subject is what the words are about, and a predicate is the actions or descriptions that apply to the subject.  For instance in the clause George is tired, George is the subject and is tired is the predicate. Adapted from Harbrace College Handbook

Independent Clause:  A clause that can make a sentence by itself; for example, He woke up in the sentence He woke up when he heard the bell.  (Longman Advanced American Dictionary)
