Correlative conjunctions are pairs of conjunctions that work together to connect words, phrases, or clauses that have equal importance in a sentence. Common examples include either...or, neither...nor, both...and, and not only...but also. These conjunctions help to create balance and clarity in writing by linking similar ideas. When using correlative conjunctions, it is important to maintain parallel structure, meaning that the elements connected should be in the same grammatical form. For instance, in the phrase "both the cat and the dog," both "the cat" and "the dog" are noun phrases. This ensures that the sentence flows smoothly and is easy to understand.
