I often get mail from people that do not know what a leprechaun is, so I have found the exact definition.
The name leprechaun is derived from the old Irish word luchorpan which means "little body."
A leprechaun is a fairy taking the appearance of a miniature old man. They are known to live in remote places. Leprechauns are solitary creatures and spend their time making shoes and brogues. If you hear the sound of his hammer when he is at work you know you have found him.
All leprechauns possesses a hidden crock of gold. If you are fortunate enough to capture a leprechaun he might reveal the location of his gold to escape. But, keep your eye on the leprechaun. If you look away, just for a moment, he will vanish.
