The word also has a variety of other meanings such as a piece of wood that has been turned on a lathe for use as a baluster, chair leg, etc.; any of various rotating shafts that serve as axes for larger rotating parts; or a spike - any holding device consisting of a rigid, sharp-pointed object.
No, it''s alright - I haven't put this posting here by mistake. You might imagine it should have gone on my Word Blog but did you know that the name was also once used in the U.S. for dragonflies:-
A Swedish legend holds that trolls use dragonflies as spindles when weaving their clothes (hence the Swedish word for dragonfly trollslända, lit. "troll's spindle") as well as sending them to poke out the eyes of their enemies. Another Swedish piece of folklore suggests they were used by the Devil to weigh people's souls.
In England they were also once known as Devil's Darning Needles whilst some uS local names include darner, darning needle, devil's darning needle, ear sewer, mosquito fly, mosquito hawk, needle, skeeter hawk, snake doctor, snake feeder, and, still in use apparently, spindle.
