A variant spelling of 'caddie' - a person who carries golf clubs and assists golfers. Can also be a given name or surname.
From Scottish 'caddie,' originally meaning 'errand boy,' derived from French cadet meaning 'younger son.' The golf sense developed in 18th-century Scotland where caddies were young men who carried clubs and knew the courses well.
Golf caddies were originally unemployed men and boys who hung around Edinburgh's Royal Mile looking for work - 'caddies' meant street loungers. The most famous caddie might be in literature: Huckleberry Finn's real name was Thomas Cadwallader, nicknamed 'Cady.'
