n.c.1600, from Irish lupracan, metathesis from Old Irish luchorpan literally “a very small body,” from lu “little” (from PIE *legwh- “having little weight;” see light (adj.)) + corpan, diminutive of corp “body,” from Latin corpus “body” (see corporeal). Commonly spelled lubrican in 17c. English. Leithbragan is Irish folk etymology, from leith “half” + brog “brogue,” because the spirit was “supposed to be always employed in making or mending a single shoe.” In the folklore of Ireland, little men who resemble elves. Supposedly, leprechauns can reveal — but only to someone clever enough to catch them — the location of buried treasure, typically a crock of gold hidden at the end of the rainbow.
