Why was clemency trending last week?
c.1200, from Old Norse und "as far as, up to" (related to Old English end; see end) + till "until, up to" (see till (prep.)). Originally also used of persons and places. Cf. Swedish intill, Danish indtil. The Modern German equivalent, bis (Old High German biaz), is a similar compound, of Old High German bi "by, at, to" and zu "to."
