A conjunction is a word which connects two words or clauses or sentences and shows the relation between them. They are used to avoid making the text seem like bullet points and to make the text flow.
These conjunctions are used to link or join two words or phrases that are equally important and complete in terms of grammar when compared with each other. That is to say, the sentences or words do not depend on anything to give themselves meaning.
These conjunctions are used to join an independent and complete clause with a dependent clause that relies on the main clause for meaning and relevance. The dependent clause cannot exist on its own as a sentence and often does not make sense without the main clause.
The subordinating conjunction always comes before the dependent clause but the dependent clause itself can be placed either ahead of or following the independent clause.
Correlative Conjunctions are simply pairs of conjunctions used in a sentence to join different words or groups of words in a sentence together. Correlative Conjunctions are generally not used to link sentences themselves, instead they link two or more words of equal importance within the sentence itself.
