Century Dictionary and Cyclopedia

1. n. A kind of paste or dough prepared, originally and chiefly in Italy, from the glutinous granular flour of hard varieties of wheat, pressed into long tubes or pipes through the perforated bottom of a vessel furnished with mandrels, and afterward dried in the sun or by low heat. The same material, called Italian paste, is also made into a thread-like product called vermicelli, and into sticks, lozenges, disks, ribbons, etc. Macaroni, cooked in various ways, constitutes a leading article of food in Italy, especially in Naples and Genoa, and it is much used elsewhere. Imitations of it are made in other countries from ordinary flour, which is much less suitable.
2. n. A medley; something extravagant or calculated to please an idle fancy.
3. n. A London exquisite of the eighteenth century; a fop; a dandy; a member of the Macaroni Club. See II., 1.
