Which type of conjunction consists of a pair of words?

Correlative conjunctions are indeed pairs of words that work together to connect equivalent elements in a sentence. Common examples include pairs such as "either...or," "neither...nor," "both...and," and "not only...but also." These conjunctions serve to link two similar grammatical structures, ensuring that the relationship between the connected elements is clear.

Understanding correlative conjunctions is essential in writing and communication, as they can enhance the flow of ideas and provide clarity in constructing complex sentences. In contrast, subordinating and coordinating conjunctions function differently; subordinating conjunctions introduce subordinate clauses and establish a relationship of dependence with the main clause, while coordinating conjunctions connect individual words, phrases, or independent clauses without forming explicit pairs. Therefore, recognizing the defining characteristic of correlative conjunctions as pairs underscores their unique role in sentence construction.
