Some food tastes better the second day you serve it, like left-over lasagna. This got me thinking about the phrase left-over, I wondered how long it’s been in use. According to the Online Etymology Dictionary (yes, there is such a thing!):
Leftover or left-over is an adjective meaning: “remaining, not used up,” originating around 1890, from left + over. The noun meaning “something left over” is from 1891; leftovers “excess food after a meal” (especially if re-served later) is from 1878; in this sense Old English had metelaf.
BONUS WORD: The word “ort”, meaning a small scrap of food left after a meal is completed, is not commonly heard in conversation, but is frequently encountered in crossword puzzles.
