What type of conjunction is 'whether-or'?

'Whether-or' is classified as a correlative conjunction. Correlative conjunctions are pairs of conjunctions that work together to connect similar elements in a sentence. They often appear in pairs and help to link clauses, phrases, or words that have equal importance. In the case of 'whether-or,' the conjunctions 'whether' and 'or' are used together to indicate a choice between two alternatives, effectively signifying an uncertainty or a conditional situation.

For instance, in the sentence "You need to decide whether to stay or leave," 'whether' introduces the choice, while 'or' provides the alternative, demonstrating how these two conjunctions collaborate to form a cohesive option. This is characteristic of correlative conjunctions, as they establish relationships between two comparable elements within a sentence, thereby enhancing clarity and depth in communication.
