Singular 'they' seems to be the preferred method of dealing with this, in British English at least. Though I'm not sure whether it's correct to say "They have a bunch of bananas" or "They has a bunch of bananas." I think, under those circumstances, I'd be inclined to refer to the person by name, if I knew it.

"Ze" pronouns are another option, though this seems to have less traction. More details here: [mypronouns.org]

Mx is frequently used in place of Mr, Mrs, Miss, Ms etc. for someone who doesn't wish to declare masculine or feminine in their title.

It's much easier in English, because English doesn't insist on gendering every noun.

@NicoleCadmium regardless, seems like broken english also.

@Mofo1953 "They has" definitely sounds broken, whereas "they have" works just fine. So even though it's singular 'they', I think, linguistically, we still need to treat it as a plural.

Even outside of non-binary identity, I suppose there are instances where we use singular 'they' to avoid being gender specific.

"The manager is here. They have asked me what the problem is."

Thank you! That might be the most comprehensive answer.

This is obviously not a decided topic yet and she's trying to do right by her students. I'll send this along.
