These two-foot tall, unfriendly, gruff men (there are no female leprechauns) prefer to pass their time making shoes for other fairies. They usually wear a green coat, a green hat, and a shoemaker's apron.
The name leprechaun may have derived from the Irish leath brogan (shoemaker), although its origins may lie in luacharma'n , Irish for small or little body or from Luch-chromain, meaning ‘little stooping Lugh'.
Due to their thrifty nature, they are trusted to guard fairy treasures and hide their pots of gold very carefully. But rainbows and the sound of a shoemaker's hammer provide humans with visual and audio cues as to the whereabouts of a leprechaun and his hidden treasure.
According to legend, If caught by a mortal, he will promise great wealth if allowed to go free. He carries two leather pouches. In one there is a silver shilling, a magical coin that returns to the purse each time it is paid out. In the other he carries a gold coin which he uses to try and bribe his way out of difficult situations. This coin usually turns to leaves or ashes once the leprechaun has parted with it. However, you must never take your eye off him, for he can vanish in an instant.
The leprechaun 'family' appears split into two distinct groups - leprechaun and cluricaun. Cluricauns may steal or borrow almost anything, creating mayhem in houses during the hours of darkness, raiding wine cellars and larders. They will also harness sheep, goats, dogs and even domestic fowl and ride them throughout the country at night.
