COORDINATE CONJUNTIONS

The simple, little conjunctions are called coordinating conjunctions.
The most commonly used coordinate conjunctions are and, but and or.In addition, the words nor and yet may be used as coordinate conjunctions, each coordinate conjunction is followed by its meaning and an example of its use. Note the use of inverted word order in the clause beginning with nor.
A coordinating conjunction can join two main clauses that a writer wants to emphasize equally. The pattern for coordination looks like this:

Main Clause + , + Coordinating Conjunction + Main Clause.

Coordinate Conjunctions:
*and: in addition
*but: however
*or: alternatively
*nor: and neither
*yet: however
*so
*for

Coordinate conjunctions are used to join two similar grammatical constructions; for instance, two words, two phrases or two clauses.
when a coordinate conjunction joins two verbs which have the same subject, the subject need not be repeated. For instance, in the example she tried and succeeded, the pronoun she acts as the subject for both the verb tried and the verb succeeded. It should also be noted that when a coordinate conjunction joins two verbs which do not have the same subject, the two coordinate clauses may be separated by a comma or semicolon, in order to make the meaning clear.
