I originally thought the pronunciation was more like hil-AIR-ee-uh, but I like the given pronunciation much more. I have been forever scarred against this name by a terrible Eragon fanfic I came across once, though.
I would like this name much more if only it was pronounced "Hill-uh-REE-uh", or, phonetically, "HILARY-uh". Don't like it's common pronunciation, sorry!
2. The beginning sounds like “Hilariously”
3. It’s not really good.
Don’t even consider it honestly.
