Don't forget that other contraption : for "those" we have "celles" + "ceux" = "celleux" (and probably celle + celui into cuielle or something)

Then let's have fun with everybody : "toutes" and "tous" is an easy one - toustes !

Checking wikipedia on the matter, TIL that until the XII century French had neutrals "al" or "el", and these are proposed for a comeback

I am sincerely 100% for the transformation of language towards eradication of the default masculine and the new pronouns, but changing habits is hard.
