Old English hwilc, from the Germanic bases of who and alike.


In US English, it is usually recommended that which be employed only for nonrestrictive (or nonessential) clauses: the horse, which is in the paddock, is six years old (the which clause contains a nonessential fact, noted in passing; the horse would be six years old wherever it was). A that clause is restrictive (or essential), as it identifies a particular thing: the horse that is in the paddock is six years old (not any horse, but the one in the paddock). See also restrictive (usage) and that.
