Conjunctions are words that are used in sentences to link two words, phrases or clauses together. Conjunctions are divided into three major classes, which are coordinating, subordinating and correlative. The coordinating conjunctions are used to joint two words, clauses or phrases together. The subordinating conjunctions are used to connect two groups of words by making one of the group to be subordinate to the other one. The correlative conjunctions are used in pairs to join elements that are equal in value.
