boggart

Alternative spelling of boggard (A bogey, a ghost)

OH! Maeſter—ſtrange things late I've ſeen— / And oft has boggart-haunted been ! / I'm ſure I's falt when ſtory's-tauld, / 'Till blude run aw' through veins ſo cauld !

“[…]Are na ye shamed, ye weak gawly, that ye darena stir ower the threshold for fear of a boggart?”

A shapeshifting monster that feeds on fear.

"A boogeyman," I said. "Sometimes known as a boggle or a boggart. It's a weak form of phobophage - a fear-eater, mostly insubstantial."

I pushed open the lid, half-expecting a Boggart to burst out of the trunk, taking the form of my worst nightmare.
