Puck (mythology)
In English folklore, Puck is a domestic and nature sprite, demon, or fairy.
"Puck" is used as a proper name of such a character, in folklore also known as Robin Goodfellow or by other names or euphemisms, but "puck" may also be used as a common noun to other groups.
Origins and comparative folklore
According to the Oxford English Dictionary, the etymology of the name Puck is "unsettled"; it is compared to Old Norse puki (Old Swedish puke, Icelandic puki, Frisian Puk).
Celtic origins (based on Welsh pwca, Cornish Bucca and Irish púca) have also been proposed, but as the Old English and Old Norse attestations are considerably older than the Celtic ones, loan from Germanic to Celtic seems more probable. The Old English púcel is a kind of half-tamed woodland spirit, leading folk astray with echoes and lights in nighttime woodlands (like the German and Dutch "Weisse Frauen" and "Witte Wieven" and the French "Dames Blanches," all "White Ladies"), or coming into the farmstead and souring milk in the churn. The etymology of Puck is examined by Katharine Mary Briggs, in Anatomy of Puck (New York: Arno) 1977.
The term pixie is in origin a diminutive of puck (compared to Swedish word "pyske" meaning "small fairy").
