Etymology

The word "whichever" combines "which," an Old English interrogative/relative pronoun (hwilc), with "ever," derived from Old English ǣfre (meaning "always" or "at any time"). The fusion creates a term that emphasizes unrestricted selection from a set. Over time, "ever" evolved to add a sense of generality or inclusivity, making "whichever" a flexible pronoun/adjective for open-ended choices.
