@charlag sibling is the thing
@f0x can I address you "dear sibling"? Sounds like "dear human life form"
@charlag @f0x It's acquiring more informality lately, I think, because it's being used more for specific individuals rather than just groups (like as a shorter way of saying "all my brothers and sisters") or hypotheticals (like "do you have any siblings?").
It's like "spouse," which I never used to hear said about one specific person but it's increasingly common, at least among subcultures that include non-binary people or just people who want to use less gendered language.
