    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.
