An archaic verb meaning to pierce through, penetrate, or make a hole in something; to run through with a sharp instrument.
From em- (intensive prefix) + pierce (from Old French percier, from Latin penetrare). The em- adds emphasis to the piercing action.
Empierce is one of hundreds of em- verbs that English experimented with—the prefix was so productive that speakers could add it to almost any verb, but most combinations never stuck around.
