- poltergeist (n.)
- 1838, from German Poltergeist, literally "noisy ghost," from poltern "make noise, rattle" (from PIE root *bhel- (4) "to sound, ring, roar;" source of bellow, bell) + Geist "ghost" (see ghost). In the native idiom of Northern England, such phenomenon likely would be credited to a boggart.
