What is "princeful"

Princeful (foaled 11 April 1991) was an Irish-bred, British-trained Thoroughbred racehorse who competed in National Hunt racing. After showing useful form in his early career, winning two National Hunt Flat races and a novice hurdle, he improved through the handicap ranks in the 1997/1998 National Hunt season before recording an upset win in the Stayers' Hurdle. He looked better than ever in the following year, winning the Long Distance Hurdle and the Long Walk Hurdle, but was brought down and badly inured in his first and only appearance in a steeplechase. He never recovered his best form thereafter and was retired from racing in 2002 with a record of seven wins and three places from eighteen races.
