the word 'spumoni' is a direct borrowing from italian, where it is the plural form of 'spumone'. 'spumone' itself derives from the italian word 'spuma', meaning 'foam' or 'froth', a descendant of the latin 'spūma' with the same meaning. the name aptly describes the dessert's light, airy texture, which was traditionally achieved by whipping the mixture. entering english in the 20th century, it retains its italian spelling and refers specifically to the layered, multi-flavored frozen confection.
