More Words, Deeper Hole

The short version is that it's really complicated and annoying. The most common workaround I've seen in French is to alternate between masculine and feminine forms ("My teacher[masc] Miss[fem] Smith is nice[masc] and pretty[fem], but sometimes too strict[masc]"), but it's clearly a workaround and not very satisfying. In Spanish the use of -x instead of gendered endings -a/-o is gaining currency, e.g., "an anthology of Latinx poets", "a collective of Chicanx artists".

It gets more complicated in languages like Japanese, where the whole way you construct a sentence and speak your words changes depending on your gender. A white male friend of mine is often asked why he speaks Japanese like a woman; it's because his teacher was a woman, and she taught him the language the way she speaks it. After a certain point you have to create an entire new way of linguistically existing. It's a challenge.
