If ばけもの / ばけもん / お化け can, in general, be understood to mean ghost/apparition/monster, what is the connection to the meaning of 化け, meaning "transform?" (or "transforming one's appearance")
Is it implying a creature transforming its appearance, or the appearance of person transforming from corporal body to ghost, or a combination thereof? (or perhaps it refers to the state of flux that a ghost exists in, or even something theater-related)
I am interested if anyone has any insight as to the etymology of the term and how it came to mean "ghost/monster".
Furthermore, does anyone have an idea if the け of 化け derives from the verb 化ける, or did the noun predate the verb?
