First appearing in English in 1830... probably originated as an alteration of 'sumptuous,' and it carries the elegant and wonderful connotations of its parent. (Sumptuous derives via Middle English from the Latin verb sumere, meaning 'to take or spend.') British author Roald Dahl had some fun with 'scrumptious,' and created a delightful coinage, when he inserted the infix '-diddly-' into the word to make 'scrumdiddlyumptious,' the word that chocolate magnate Willy Wonka uses to name his best-selling treats in his novel Charlie and the Chocolate Factory (1964).
