The origins of invincible are easily subdued. The word derives, via Middle French, from Late Latin invincibilis—a combination of the negative prefix in- with vincibilis, an adjective meaning "conquerable," from the Latin verb vincere, "to conquer." Other descendants of vincere in English include convince, evince, vanquish, and even victor. Vincere also gave English vincible, meaning (unsurprisingly) "capable of being overcome or subdued," though it is significantly less common than invincible.
