Both the adjective "impuissant" and the noun "impuissance" came to English from Middle French. They are derived from the prefix in- (meaning "not") and the noun "puissance," which means "power" and is a word in English in its own right. Puissance derives from the verb poer, meaning "to be able or "to be powerful," and is ultimately related to the same Latin roots that gave us words such as "power" and "potent." While both "puissant" and "impuissance" first appeared in English during the 15th century, "impuissant" did not make its first appearance in our language until 1629.
