Person should get a new pronouns attribute. It may contain one or more gendered or non-gendered pronouns.

Hi, I don't know if you already considerd that but besides the gender property (which you solved well by defining it as GenderType|Text) there's an increasing use of pronouns on the web so what do you think of adding it as a property?

@zichy Is this issue inspired by this discussion (just asking for linking purposes)?

@shaedrich It‘s not inspired by this discussion, but you may link the two. I searched all issues for pronouns, but forgot to have a look into the discussions.

Okay, cool! So we got the same idea independently—even better 👍

I guess, for the link to work, you must add it to the first post of this issue:

Since this could be a simple fix, does anyone know how long it might take to implement this feature?

[shaedrich]

I guess, #1112 has been a similar change. That doesn't look much, does it?

[zichy]

It really doesn't.

Any updates on this? 🙏

@zichy Indeed: I just created a PR 🎉
