c.1400, from Old French violacion and directly from Latin violationem (nominative violatio) "an injury, irreverence, profanation," from past participle stem of violare "to treat with violence, outrage, dishonor," perhaps an irregular derivative of vis "strength, force, power, energy," from PIE root *weie- "to go after, pursue with vigor or desire," with noun derivatives meaning "force, desire" (see venison).
