German - ostensibly a Germanic language - has three genders (feminine, masculine, and neuter).
English - also a Germanic language - has (aside from archaic remnants) only one gender, or no gender, depending upon how you look at it.
I don't know of any language which employs an "x"-ending to indicate neutrality. Maybe Basque?!
Since we're speaking English, why don't we continue using the already-established gender-free term Latin (e.g., "Latin lover," "Latin languages," etc.) which had been commonplace in this country up until only recently?
Regards,
What only one gender in English? What happened to he, she, and it?
