Connectors : Conjunction

A conjunction is a word that connects other words or group of words. In other word, it joins two parts of sentence.

Here are some examples of conjunctions :

Coordinating Conjunctions	Subordinating Conjunctions
and, but, or, nor, for, yet, so	although, because, since, unless

Conjunction has three basic forms :

1. Single Word

for example: and, but, because, although

2. Compound (often ending with as or that)

for example: provided that, as long as, in order that

3. Correlative (surrounding an adverb or adjective)

for example: so...that

Conjunctions have two basic functions :

1. Coordinating conjunctions are used to join two parts of a sentence that are grammatically equal. The two parts may be single words or clauses, for example:

- Jack and Jill went up the hill.

- The water was warm, but I didn't go swimming.

2. Subordinating conjunctions are used to join a subordinate dependent clause to a main clause, for example:

- I went swimming although it was cold.
