Lexember 7th: kwihin, "sharp, pointed; irritable"

An unexpected gap: kwihin /ˈkʷi.xin/ sharp, pointed. That is, it can refer to sharpness for both a blade and a point (a common enough polysemy):

Ën ausan në tanui kwihin no tul?
this blade TOP sufficiently sharp be.PFV Q
Is this knife sharp enough?

Ha në kwihin motiën kwan suillo.
1SG TOP sharp branch with jab.PFV
I jabbed it with a sharp stick.

When used referring to people, it means irritable.

Ël në kwihin ënni no rui.
3SG TOP irritable today be.PFV MIR
Wow, he's irritable today.

A word like this can regularly refer to some quality of pain, but I haven't yet decided if I'm going to use kwihin for that.
