The origins of "invincible" are easily subdued. The word derives, via Middle French, from Late Latin "invincibilis," which was itself formed by combining the negative prefix "in-" with "vincere," meaning "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."
