The History of Vulnerable

Superheroes are often depicted in comic books and movies as all-powerful, deflecting boulders and missiles in mid-air with a flick of the wrist, walking through walls, and having indestructible skeletons and whatnot. Fans know, however, that even the mightiest, meatiest protagonist is vulnerable to something, be it kryptonite or forgetting the whereabouts of one’s hammer. Vulnerable ultimately comes from the Latin noun vulnus, meaning “wound,” by way of the Late Latin adjective vulnerabilis, which English speakers adopted as vulnerable in the early 1600s. Vulnerable continues to carry its original meaning of “capable of being physically wounded,” but since the late 1600s it has also been used figuratively to suggest a defenselessness against non-physical attacks. In other words, someone (or something) can be vulnerable to criticism or failure as well as to literal wounding—even superheroes. So don’t go breaking their hearts, even if you can’t break their bones.
