"Bugbear" sounds like some kind of grotesque hybrid creature from fable
or folklore, and that very well may be what the word's creator was
trying to evoke. When the word entered English in the 16th century, it
referred to any kind of creature made up to frighten someone—most often a
child; in 1592, Thomas Nashe wrote of "Meere bugge-beares to scare
boyes." The word combines "bug," an old word for goblin, with "bear,"
which is perhaps what such made-up creatures were described as
resembling. The "source of dread or annoyance" sense came not long
after. In the late 20th century, the word found new life as the name of a
particular kind of creature in the role-playing game Dungeons &
Dragons.
Thought for the day
A life spent making mistakes is not only more
honorable but more useful than a life
spent doing nothing.
