syntax

Words which connect words, phrases, clauses or sentences are called conjunctions (see "to conjoin" = join, unite). The most common ones are 'and', 'or' and 'but'. These words all have different nuances and connotations but they all help to build up meaningful relationships within a sentence.

Definition

coordinating conjunctions

used to connect two independent clauses

subordinating conjunctions

used to establish the relationship between the dependent clause and the rest of the sentence

correlative conjunctions

used to join various sentence elements which are grammatically equal

Coordinating Conjunctions

Comes usually in the middle of a sentence, and a comma is used before the conjunction (unless both clauses are very short). They join individual words, phrases, and independent clauses.

Whereas coordinating conjunctions join parts of a sentence, the purpose of transitional words and phrases usually is to join two 'sentences'.

Examples:

We can draw lessons from the past, but we cannot live in it. [Lyndon B. Johnson]

The purpose of most computer languages is to lengthen your resume by a word and a comma. [Larry Wall]

And, but, for, nor, or, so, and yet — are the seven coordinating conjunctions. To remember them, the acronym FANBOYS can be used.

F = for

A = and

N = nor

B = but

O = or

Y = yet

S = so

Subordinating Conjunctions

Also called subordinators, introduce a dependent clause. These adverbs that act like conjunctions are placed at the front of the clause - and a comma is needed at the end of the adverbial phrase when it precedes the main clause.

Examples:

If the only tool you have is a hammer, you tend to see every problem as a nail. [Abraham Maslow]

Some people make headlines while others make history. [Philip Elmer-DeWitt]
