What does whether mean?
Whether is a standard English conjunction that introduces an indirect question or weighs two possible courses of action. It commonly appears in phrases such as “whether to proceed” and in constructions that explicitly offer alternatives, as in “whether to stay or leave.” When it introduces a question about whether something is the case, it corresponds closely to “if”: “She asked whether the office was open” means that she asked about the office’s status. The distinction is especially useful in formal edited writing, where “whether” is preferred in embedded yes-or-no questions, though “if” remains common in speech. Whether also allows a choice to be framed without making either option seem inherently preferable. Its directness and flexibility make it valuable in questions, judgments, announcements, and discussion, while its frequent pairing with “or not” gives it a familiar but emphatic rhythm.

"She could not tell whether the message was meant to be read aloud or kept private."
"I still have not decided whether I should call."
"The guide will explain whether to climb directly or to follow the longer path."
Whether turns a yes-or-no question into one graceful tool: it can ask about facts, weigh alternatives, or suggest that an outcome will not change the decision.

Where does whether come from?
The word comes from Old English hwæþer, an interrogative and conjunction meaning “whether.” It developed from Proto-Germanic *hwēþer-, ultimately associated with a Proto-Indo-European interrogative and alternative form; cognates include German ob and Dutch of, both of which can mean “if” or “whether.” English forms such as whatever, wherever, and whichever preserve related constructions built on Old English interrogative stems.
How whether is actually used
The word is neutral in register and common in both speech and formal writing. In formal edited prose, whether is often preferred for an embedded yes-or-no question, although if is widely used in ordinary speech. It is also frequently followed by an infinitive introduced by to.
