Conjunctions are mainly used to join actions, ideas and thoughts. They are categorised into three main types:
1. Coordinating conjunctions – used to combine two independent clauses. Examples of coordinating conjunctions are for, and, nor, but, or, yet and so.
2. Subordinating conjunctions – used to combine an independent clause and a dependent clause. Examples of subordinating conjunctions are if, although, though, after, before, because, as if, unless, until, when, while, etc.
3. Correlative conjunctions – used to combine two phrases or parts of the sentence which have equal importance within a sentence. Examples of correlative conjunctions are not only…but also, either…or, neither…nor, whether…or, rather…or, if…then, etc.
