KanjiJLPT N4
Dreadful

dreadful, be frightened, fearful

Mnemonic

A spirit draped in old, tattered fabric floats silently toward you in a dark hallway. The fabric spreads wide open, revealing nothing underneath—just a hollow void where a body should be. That faceless, empty presence drifting closer is utterly dreadful.
Additional thoughts
Picture the classic ghost image: a spirit hidden beneath a sheet of fabric. But this one is worse—when the fabric parts, there's nothing there at all. The emptiness is what makes it truly terrifying. Spirit (heart radical) + Fabric = Dreadful.
Quick recall
A spirit cloaked in fabric reveals hollow emptiness beneath—absolutely dreadful.
