impeach (v.) Look up impeach at Dictionary.com
formerly also empeach, late 14c., "to impede, hinder, prevent," from Anglo-French empecher, Old French empeechier "to hinder, stop, impede; capture, trap, ensnare" (12c., Modern French empêcher), from Late Latin impedicare "to fetter, catch, entangle," from assimilated form of in- "into, in" (from PIE root *en "in") + Latin pedica "a shackle, fetter," from pes (genitive pedis) "foot" (from PIE root *ped- "foot"). Sense of "accuse a public officer of misconduct" first recorded 1560s, perhaps via Medieval Latin confusion of the word with Latin impetere "attack, accuse" (see impetus).
