A being or person that is half-devil or partially evil; someone who is somewhat wicked or devilish.
From demi- (half) + devil (an evil supernatural being). Following the productive demi- pattern, this creates a term for something partway between human and demonic.
Medieval bestiaries and moral tales were full of creatures that were part-human, part-demon—this word perfectly names those ambiguous creatures caught between good and evil, like the mischievous imps that caused trouble without outright malice.
