From my preschooler:
What's an Achashvei?
I know that a rosh is a head. I want to know what kind of head Achashveirosh was.
Can you help me come up with a satisfying answer? I'd prefer not to have to rely on some sort of academic cop-out like saying the word is actually Ugaratic (whatever that is) or one of these other non-Lashon-Hakodesh languages that, they say, somehow snuck into Tanach, chas veshalom.
