LUNCHEON  , in

present usage the name given to a meal between breakfast and tea or dinner . When dinner was taken at an early hour, or when it is still the principal midday meal, luncheon was and is still a light repast . The derivation of the word has been obscured, chiefly owing to the attempted connexion with " nuncheon," with which the word has nothing to do etymologically . " Luncheon " is an extended form of " lunch " (another form of " lump," as " hunch " is of " hump ") . Lunch and luncheon in the earliest meanings found are applied to a thick piece of bread, bacon, meat, &c . The word " nuncheon," or " nunchion," with which "luncheon" has been frequently connected, appears as early as the 14th century in the form noneschenche . This meant a refreshment or distribution, properly of drink, but also accompanied with some small quantity of meat, taken in the early afternoon . The word means literally " noon-drink," from none or noon, i.e. nona hora, the ninth hour, originally 3 o'clock P.M., but later " midday "—the church office of "nones," and also the second meal of the day, having been shifted back—and schenchen, to pour out; cf . German schenken, which means to retail drink and to give, present . Schenche is the same as "shank," the shin-bone, and the sense development appears to be shin-bone, pipe, hence tap for drawing liquor .
