afterward

The word "afterward" is a compound formed entirely within Old English. Its first element, "after," originates from the Proto-Germanic comparative form aftaro-, meaning "further behind, later," which itself derives from the Proto-Indo-European root apotero-, a comparative of apo- meaning "off, away." The second element is the directional suffix "-ward," from Proto-Germanic -warth-, indicating direction or tendency. Literally, "afterward" means "in a direction toward what comes after." Over time, this spatial sense evolved into a purely temporal one, solidifying its modern meaning of "at a subsequent time." The spelling variant "afterwards" simply adds the common adverbial genitive '-s'.
