From Middle English accioun, accion, from Old French aucion, acciun, from Latin āctiō(n) (“act of doing or making”), from āct(us) + action suffix -iō(n), perfect passive participle of agere (“do, act”), ultimately from Proto-Indo-European *h₂éǵeti. See also act, active. By surface analysis, act + -ion.
