EX'PI-ATE, v.t. [L. expio; ex and pio, to worship, to atone; pius, pious, mild. The primary sense is probably to appease, to pacify, to allay resentment, which is the usual we of atone in most languages which I have examined. Pio is probably contracted from pico, and from the root of paco, the radical sense of which is to lay, set or fix; the primary sense of peace, pax. Hence the sense of mild in pius. But this opinion is offered only as probable.]
