défense (French)

Where does "défense" come from?

The French noun defense is inherited from Old French, drawing ultimately from the Late Latin defensa[1]. This Late Latin form is a nominalization of the feminine perfect passive participle of the Latin verb defendo[1][3]. The verb itself combines de with fendto, meaning to hit or thrust[2]. Reaching further back, this root stems from Proto-Italic and the Proto-Indo-European root gwhen meaning to strike or to kill[2]. Over time, the word expanded in French to cover meanings ranging from protection and prohibition to animal tusks.
