Angels-GOBLINS

In contemporary English, goblin connotes an evil spirit, sort of a small
demon. Originally goblins were a grotesque tribe of fairies who
delighted in frightening people with malicious pranks, such as the
kind of activities one associates with poltergeists. They could, however,
also be helpful around a house, in the same way that brownies
could be helpful. The expanded term hobgoblin was originally reserved
for helpful goblins. However, perhaps because the Puritans used goblin
and hobgoblin to designate evil spirits, both words eventually acquired
demonic connotations.
