  • Usage notes

    * 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?''
    Further, in the first two of these examples, the "or staying" and "or not" may be added as an afterthought (sometimes indicated in writing with a comma before), such that the ''whether may be uttered in sense 3 and then amended to sense 2. * 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.
