    Usage notes

    * (US usage'') Some authorities insist, prescriptively, that relative ''which'' should be used only in non-restrictive contexts. For restrictive contexts (e.g., ''The song that made the charts in 2004 is better than the later ones''), they prefer ''that''. Actual usage does not support this "rule". Fowler, who proposed the rule, himself acknowledged that it was "not the practice of most or of the best writers". Even E.B. White, a notorious "which-hunter", wrote this: "the premature expiration of a pig is, I soon discovered, a departure which the community marks solemnly on its calendar." In modern UK usage, ''The song which made the charts in 2004 is better than the later ones is generally accepted without question. * When "which" (or the other relative pronouns "who" and "that") is used as the subject of a relative clause, the verb agrees with the antecedent of the pronoun. Thus "The thing which is...", "The things which are...", etc.

  • 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.
