Referring to older nonbinary sibling when talking to others

[d-hermit]

I don’t think omitting the topic makes the sentence informal.

Btw, just so that you don’t feel bad about not being able to translate an English expression directly into another language, in Russian there’s not even a word for a “sibling”. So if you want to avoid using a gendered sister/brother you’d say “my parents have another child besides me”. That would sound very peculiar but I guess it can’t be helped since the concept of non-binary is so new and uncommon in the Russian speaking society.

I am rusty on my Russian (haven’t used it in years), but I didn’t think of that. I guess it will take time for the languages to catch up.
