english, spanish and french:

man used to unambiguously mean human, of either gender. the english word for (male) man was were (as in werewolf), which has fallen in disuse. needless to say: man still doesn't refer exclusively to males, so in a sense men don't have a word of their own any more.

the word for woman was wife (pronounced weefeh in old english), and woman itself comes from wifeman, female person (i guess the singular pronunciation with the "o" is due to vowel harmony).

same deal in spanish: hombre comes from latin homo which is gender neutral. mujer comes from latin mulier: woman.

in french, again, homme from homo, femme from femina: female. just like "man", "homme" and "hombre" doesn't necessarily imply male sex as it often implies humanity.

italian and german:

you can easily guess the etymologies of "uomo" and "Mann" and their clumsy attempt at filling the void left by the extinct "vir" and "Wer" but here it's where it gets interesting:

italian did they same to mulier as english did to wife, which is to say moglie means wife rather than woman, but this time it was replaced by donna, a contraction of domina, which means female master or lord. women are quite literally called masters in italian and it's been the case since the middle ages.

in german, similarly, Weib has been (predominantly) replaced by Frau, which in olden times was a title of nobility akin to lord (a good analogy would be "lady" replacing "woman" in english).

​

so, while men lost the specific word to distinguish them from women, but rather generic one that simply doesn't take away the possibility of maleness, women either got to keep theirs or exchange it for a status symbol, thereby fusing femaleness with authority and prestige. in italy, this last thing happened in the misogynistic middle ages, yet i've known people around the world, even in neighboring austria, who are convinced that italian women are men's property to this day.
