To make sure I have this straight, they have a one-word term for me.

But if I'm to refer to them, I have to say {be'nalwI' tey'pu'} "my wife's nieces/nephews" (or "niece/nephew-in-law").

Also, I just realized that if one had a transgender sibling who transitioned after having children, the terms for their children would switch.

That "World's best {lor}" mug would suddenly be awkward.
