In India they recognize three genders
Male, Female and Hijra
In Spanish perhaps children of the three genders can be called
Nino, Nina, and Nine
(pretend that there is the little squiggle over the second 'n' of each!)
(and it's ninyay, not '9'! Like to rhyme with 'Nino' and 'Nina'! I don't think the 'e' would ever be silent after an 'n' with the squiggle over it! (But I don't have an 'n' with a squiggle over it on my computer keyboard!))
Why not?
God loves you! Whatever you are!
(For whatever you are, you have just as much capacity for kindness!)
Sincerely,
David S. Annderson
