- Bible, Matthew xxi. 31
- Whether of them twain did the will of his father?
- 1616, William Shakespeare, King John, I.i:
- Whether hadst thou rather be a Faulconbridge, [...] Or the reputed sonne of Cordelion?
- Used to introduce an indirect interrogative question that consists of multiple alternative possibilities (usually with correlative or).
- He chose the correct answer, but whether by luck or by skill I don't know.
- Without a correlative, used to introduce a simple indirect question; if, whether or not.
- Do you know whether he's coming?
- Used to introduce a disjunctive adverbial clause which qualifies the main clause of the sentence (with correlative or).
- He's coming, whether you like it or not.
- There is some overlap in usage between senses 2 and 3, in that a yes-or-no interrogative content clause can list the two possibilities explicitly in a number of ways:
- Do you know whether he's coming or staying?
- Do you know whether he's coming or not?
- Do you know whether or not he's coming?
- Sense 4 does not have a counterpart that introduces only a single possibility; *"He's coming, whether you like it" is ungrammatical.
- In traditional grammar, the clauses headed by whether in senses 2 and 3 are classified as noun clauses, and those headed by whether in sense 4 are classified as adverb clauses.
