"tube-shaped food made of dried wheaten paste" [Klein], 1590s, from southern Italian dialectal maccaroni (Italian maccheroni), plural of maccarone, name for a kind of pasty food made of flour, cheese, and butter, possibly from maccare "bruise, batter, crush," which is of unknown origin, or from late Greek makaria "food made from barley."

Originally known as a leading food of Italy (especially Naples and Genoa), it was used in English by 1769 to mean "a fop, a dandy" ("typical of elegant young men" would be the sense in "Yankee Doodle") because it was an exotic dish in England at a time when certain young men who had traveled the continent were affecting French and Italian fashions and accents (and were much mocked for it).

There is said to have been a Macaroni Club in Britain by 1764, composed of young men who sought to introduce elegancies of dress and bearing from the continent, which was the immediate source of this usage in English. Hence the extended use of macaroni as "a medley; something extravagant to please idle fancy" (by 1884).

1610s, "small sweet cake made of ground almonds (instead of flour) and whites of eggs," from French macaron (16c.), from dialectal Italian maccarone, the name of a kind of pasty food made of flour, cheese, and butter (see macaroni). The French meaning is said to have been introduced 1552 by Rabelais. The -oon ending was conventional in 15c.-17c. English to add emphasis to borrowings of French nouns ending in stressed -on.

1610s, in literature, in reference to a form of verse consisting of vernacular words in a Latin context with Latin endings; applied loosely to verse in which two or more languages are jumbled together with little regard to syntax but so constructed as to be intelligible; from Modern Latin macaronicus (coined 1517 by Teofilo Folengo, who popularized the style in Italy), from dialectal Italian maccarone (see macaroni), in reference to the mixture of words in the verse: "quoddam pulmentum farina, caseo, botiro compaginatum, grossum, rude, et rusticanum" [Folengo].

1883, "fastidious man," New York City slang of unknown origin; recent research suggests it is a shortening of Yankee Doodle, based on the song's notion of "foppish, over-fastidious male" (compare macaroni). The vogue word of 1883, originally used in reference to the devotees of the "aesthetic" craze, later applied to city slickers, especially Easterners vacationing in the West (as in dude ranch "ranch which entertains guests and tourists for pay," attested by 1921). "The term has no antecedent record, and is prob. merely one of the spontaneous products of popular slang" [Century Dictionary].

Now, "tenderfoot" is not to be construed as the Western equivalent of that much evolved and more abused specimen of mankind, familiarly styled "dude." For even the Montana cowboy recognizes the latter. Not that he has ever seen the true prototype of a class that was erstwhile so numerous among us. But he is convinced that a person caught in the act of wearing a white linen collar, and who looks as though he might have recently shaved or washed his face, must be a dude, true and proper.

Application to any male is recorded by 1966, U.S., originally in African-American vernacular.

a generic name for Italian dough-based foods such as spaghetti, macaroni, etc., 1874, but not common in English until after World War II, from Italian pasta, from Late Latin pasta "dough, pastry cake, paste," from Greek pasta "barley porridge," probably originally "a salted mess of food," from neuter plural of pastos (adj.) "sprinkled, salted," from passein "to sprinkle," from PIE root *kwet- "to shake" (see quash).

species of hard wheat especially used in making macaroni, by 1904, from Latin durum, neuter of durus "hard," from PIE *dru-ro-, suffixed variant form of root *deru- "be firm, solid, steadfast." The seeds are tough. It was introduced in the U.S. by the Department of Agriculture in 1899 from Russia and 1900 from North Africa.

Previous to 1901 this wheat could not usually be sold at the elevators or mills at any price and was rarely grown—in small quantities only, for stock feed. Since its commercial value has been demonstrated the production has increased from 100,000 bushels, the largest estimate in 1901, to at least 6,000,000 bushels in 1903—an increase of sixtyfold in two years. [Flour Trade News, November 1904]

1683, a name applied disparagingly by Dutch settlers in New Amsterdam (New York) to English colonists in neighboring Connecticut. It may be from Dutch Janke, literally "Little John," diminutive of common personal name Jan; or it may be from Jan Kes familiar form of "John Cornelius," or perhaps an alteration of Jan Kees, dialectal variant of Jan Kaas, literally "John Cheese," the generic nickname the Flemings used for Dutchmen.

[I]t is to be noted that it is common to name a droll fellow, regarded as typical of his country, after some favorite article of food, as E[nglish] Jack-pudding, G[erman] Hanswurst ("Jack Sausage"), F[rench] Jean Farine ("Jack Flour"). [Century Dictionary, 1902, entry for "macaroni"]

Originally it seems to have been applied insultingly to the Dutch, especially freebooters, before they turned around and slapped it on the English. A less-likely theory (attested by 1832) is that it represents some southern New England Algonquian language mangling of English. In English a term of contempt (1750s) before its use as a general term for "native of New England" (1765); during the American Revolution it became a disparaging British word for all American natives or inhabitants. Contrasted with southerner by 1828. Shortened form Yank in reference to "an American" first recorded 1778. Latin-American form Yanqui attested in English by 1914 (in Mexican Spanish by 1835).

The rule observed in this country is, that the man who receives that name [Yankee] must come from some part north of him who gives it. To compensate us for giving each other nicknames, John Bull "lumps us all together," and calls us all Yankees. ["Who is a Yankee?" Massachusetts Spy, June 6, 1827]
