I have questions, as an English-speaking French and Spanish learner. 

In none of my classes, they never covered how to nickname or refer to someone who is non-binary/intersex/gender-fluid/etc. So, what do y’all do? I thought, maybe just mixing the gender of the word with the “incorrect” article (i.e., “mon cherie” because “mon” is masculine” but “cherie” is the feminine form, or “cariña mio” along those same lines.) But is that like... all? Is there anything else to do? 

And then like, what about if you’re referring to them in the third person? In Spanish I imagine it’s easier because you don’t have to have a pronoun, but in French? Is it like... default to “on” instead of il or elle? But “on” is for a group of indefinite specificity, not an individual.
