I’ve heard (debated) etymology that “man” is gender neutral because in older English, “male” would have been “wereman” and “female” would have been “wifman,” so the “man” morpheme just designated “human” and the prefix designated the gender.
Which does imply that "were"wolves are exclusively male, and a female wolf person really should be called a wifwolf.
Did you mean the 25th amendment? Article 12 just describes the process for electing the president and VP.
