Literally all of them?

Unless you count theoretical math or forms of poetry as inventions, yeah. 

I might be inclined to. There are cultural and possibly even genetic differences among humans but none that stark even counting math and poetry, though.

It might be entirely cultural. We did self-sort pretty recently.

How did that go down?

When the Vanyar decided to leave Tirion and move closer to Taniquetil. People mostly went by their ethnic group but not entirely.

So there are like, adopted Vanyar?

Married in, usually. And more the other way around. But yeah. I wouldn't consider someone a Vanya if they stayed in Tirion and consider my father their King and so on, whatever their hair color. Well, I do think of my father's second wife as one, but I am maybe a bit irrational about her because she's so unlikeable.

You know the English word is "stepmother", right?

The Quenya too. I don't find it accurate.

Why?

She is not any kind of mother to me and doesn't have a relationship with me beyond being married to my father.

The English concept covers a wide variety of things up to and including "repeated murder attempts", if you just inject the word with sufficient venom no one is going to assume that you call her Mom and sit next to her at holiday dinners.

Text doesn't have a way of indicating tone.

Familiarity with your opinion would have filled in for me fine.

I guess. I just - at home people will assume that you call her 'mom' and sit next to her at festivals.

That sounds irritating. If you need the extra emphasis the repeated murder attempt version is glossed as "wicked stepmother", people will assume facetiousness but not to the point of implied affection?

She is not a bad person she is just a person I don't consider family in any respect, affectionate or otherwise. And the kids are too young to have done anything wrong, a venomous 'half-sibling' wouldn't be fair, but they're not. Siblings. Not even halfway.

I think you are asking your word choice to do a lot of work it isn't cut out for.

Do you think people would actually be confused by it? As opposed to disapproving.

I could imagine people figuring they're stepsiblings and not half-siblings depending on how you brought them up and how they resolved resulting uncertainty.

Oh, I refer to them as my father's children by his second wife.

That's sort of... technically clear? But one time somebody went around with a petition to ban dihydrogen monoxide and told no literal falsehoods and people signed it. The phrase is deliberately obtuse in a way that could lead people to think you're adopted, or they're older than you and you're from wife #3, or something.

Maybe one of them will turn out to be an interesting person and I won't mind calling him a brother.

I'm gonna drop this subject before I have to tell Rete to take over talking to you again.
