Either vs. Whether: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Updated on October 3, 2023
"Either" indicates one of two choices, while "Whether" introduces alternatives or expresses uncertainty.

Key Differences
"Either" and "Whether" are both conjunctions in English grammar, but they serve different purposes. "Either" typically indicates a choice between two alternatives. It can also function as an adjective or pronoun, often pointing out one or the other of two entities.

On the other hand, "Whether" is used to introduce indirect questions or to indicate doubt or a choice between alternatives. It often precedes clauses that present two or more alternatives, not just two as in the case with "Either." "Whether" does not have the flexibility of functioning as an adjective or pronoun like "Either" does.

To further understand, consider the sentences: "You can have either chocolate or vanilla" and "I'm not sure whether I want chocolate or vanilla." In the former, "Either" presents two clear choices, while in the latter, "Whether" shows uncertainty in choosing.

In essence, while both "Either" and "Whether" involve options or choices, "Either" specifically points to one of two options, and "Whether" introduces a doubt or multiple possibilities without limiting them to just two.
