Plural of cud; the portions of food that grazing animals regurgitate to chew again.
From Old English 'cudu,' related to Old High German 'chouwon' meaning to chew; the meaning has remained consistent for over a thousand years.
Cows chew cud to maximize nutrient extraction—it's like having a second chance to break down tough plant fibers that their single stomach chamber can't fully digest on first try.
