From Middle English quiten, quyten, from Anglo-Norman quitter, Old French quitter, from quitte (“acquitted, quit”), ultimately from Latin quietus, which itself derives from Proto-Indo-European kʷyéh₁-ti-s, from kʷyeh₁- (“to rest”). Doublet of coy, quite, quiet, and quietus. Compare Dutch kwijten (“to quit”), German Low German quitten (“to quit”), German quitten, quittieren, Danish kvitte, Swedish qvitta, kvitta (“to quit, leave, set off”), Icelandic kvitta.

The verb is transitive when referring to a job or a program, but can be intransitive when referring to the general act of stopping.
