Nuncheon

Nuncheon
Definition: a light midmorning or midafternoon snack consisting typically of bread, cheese, and beer

What about second breakfast? What about elevenses? Luncheon? Afternoon tea? Dinner? Supper? You know about them, don’t you? Okay, dear hobbit, but do you know about nuncheon? Nuncheon, in fact, may be thought of as a synonym of elevenses, being a light midmorning snack, except that it can also refer to a light midafternoon snack, and typically involves beer (nuncheon comes from the Middle English word noneschench, meaning literally “noon drink”).

The etymology of this word is a puzzle of long standing. The guess-work writers have long ago made the desperate attempt to connect it with noon-shun, because (note the ‘because,’ that marks the work of your guesser) labourers shun the heat of noon when they eat their nuncheon. But of course it is obvious that the labourer does not shun the noon itself, but only the heat of it. When the etymology of a word is unknown, there is but one thing to do, viz. to wait in patience till the light comes.
