CONJUNCTIONS
Conjunctions are words used as joiners.
Different kinds of conjunctions join different kinds of grammatical structures.
The following are the kinds of conjunctions:
       
A. COORDINATING CONJUNCTIONS (FANBOYS)
            for, and, nor, but, or, yet, so
Coordinating conjunctions join equals to one another:
            words to words,          phrases to phrases,          clauses to clauses.
         
Coordinating conjunctions usually form looser connections than other conjunctions
do.
Coordinating conjunctions go in between items joined, not at the beginning or end.
       Punctuation with coordinating conjunctions:
When a coordinating conjunction joins two words, phrases, or subordinate clauses,
no comma should be placed before the conjunction.
           
A coordinating conjunction joining three or more words, phrases, or subordinate
clauses creates a series and requires commas between the elements.
           
A coordinating conjunction joining two independent clauses creates a compound
sentence and requires a comma before the coordinating conjunction
          
   
        
B. CORRELATIVE CONJUNCTIONS
                either. . .or              both. . . and
                neither. . . nor           not only. . . but also
             
These pairs of conjunctions require equal (parallel) structures after each one.
C. CONJUNCTIVE ADVERBS
These conjunctions join independent clauses together.
The following are frequently used conjunctive adverbs:
    after all                      in addition                 next
    also                           incidentally                nonetheless
    as a result                    indeed                      on the contrary
    besides                        in fact                     on the other hand
    consequently                   in other words              otherwise
    finally                        instead                     still
    for example                    likewise                    then
    furthermore                    meanwhile                   therefore
    hence                          moreover                    thus
    however                        nevertheless                 
    Punctuation    Place a semicolon before the conjunctive adverb and a comma after
    :              the conjunctive adverb.
     
D. SUBORDINATING CONJUNCTIONS
These words are commonly used as subordinating conjunctions
    After                     in order (that)              Unless
    Although                  insofar as                   Until
    As                        in that                      When
    as far as                 Lest                         whenever
    as soon as                no matter how                Where
    as if                     now that                     wherever
    as though                 Once                         whether
    Because                   provided (that)              While
    Before                    Since                        Why
    even if                   so that
    even though               supposing (that)
    How                       Than
    If                        That
    inasmuch as               Though
    in case (that)            Till
Subordinating conjunctions also join two clauses together, but in doing so, they
make one clause dependent (or "subordinate") upon the other.
A subordinating conjunction may appear at a sentence beginning or between two
clauses in a sentence.   
A subordinate conjunction usually provides a tighter connection between clauses
than a coordinating conjunctions does.
Loose:          It is raining, so we have an umbrella.
Tight:          Because it is raining, we have an umbrella.
    Punctuation Note:
    When the dependent clause is placed first in a sentence, use a comma between the two clauses. 
    When the independent clause is placed first and the dependent clause second, do not separate th
    two clauses with a comma.
