Coordinating conjunctions are used to link two independent sentences (clauses) into one compound sentence. Coordinating Conjunctions are: and, but, for, or, so, yet, and nor. A coordinating conjunction that joins two clauses is normally preceded by a comma.
The specific coordinating conjunction used to link two sentences depends on the logical relationship between the clauses. Coordinating conjunctions used in short clauses is not preceded by comma (sometimes, not always).
See the table below:
|And, But, For, Or, So, Yet, and Nor|
|My wife is sociable,||and she can be quite nice.||And = addition|
|but she has few friends.||But = contrast|
|for her is very secure.||For = reason|
|or at least she acts that way.||Or = choice|
|so many people like her.||So = result|
|yet she doesn’t like to go to parties.||Yet = contrast|
|My wife is not sociable.
She is not very polite.
|My wife is not
sociable nor is she polite.
|Nor is used to link two negative sentences.
When nor begins the second clause, the
auxiliary (or the verb “be”) is placed before
the subject (she – in this example).
The negative (“not”) in the second clause
