cigar-shaped tubes of fried pastry filled with sweetened ricotta, a Sicilian dessert, 1948, from Italian cannoli, plural of cannola, literally "small tube," from Latin cannula "small reed or pipe," diminutive of canna "reed, pipe" (see cane (n.)).
c. 1400, "artillery piece, mounted gun for throwing projectiles by force of gunpowder," from Anglo-French canon (mid-14c.), Old French canon (14c.), from Italian cannone "large tube, barrel," augmentative of Latin canna "reed, tube" (see cane (n.)). The double -n- spelling to differentiate it from canon is from c. 1800. Cannon fodder (1847) translates German kanonenfutter (compare Shakespeare's food for powder in "I Hen. IV").
