And from dictionary.com comes the word history of leprechaun, which I know you were just dying to know, and now, you do, and so living comes easily to you.
Word History: Nothing seems more Irish than the leprechaun; yet hiding within the word leprechaun is a word from another language entirely. If we look back beyond Modern Irish Gaelic luprachán and Middle Irish luchrupán to Old Irish luchorpán, we can see the connection. Luchorpán is a compound of Old Irish lú, meaning “small,” and the Old Irish word corp, “body.” Corp is borrowed from Latin corpus (which we know from habeas corpus). Here is a piece of evidence attesting to the deep influence of Church Latin on the Irish language. Although the word is old in Irish it is fairly new in English, being first recorded in 1604.
