peace (2)
zero derivation; verb
Peace, V - To leave [Metaphorical conversion from Noun to Verb of original root morpheme, no new affixes added]
Etymology : The usage of this word as verb seems to show origin in the practice of wishing people 'peace' as you leave a conversation or meeting (ie, 'I'm going to leave guys, peace'). The word shows conversion from noun to verb, taking the idea of a goodbye wish and transforming it into the action of departing. Peace comes from Anglo-Norman peas to Old French paix meaning 'to have tranquil relationships with' (OED).
