Stomach, digestion, food
Gastro- comes from Greek "gaster/gastros" (stomach, belly) and appears in both medical and culinary vocabulary. Gastronomy = the laws of the stomach (the art of fine eating); gastritis = inflammation of the stomach; gastrointestinal = of the stomach and intestines; gastropod = stomach-foot (snails move on a muscular foot beneath the belly). Spanish uses the same prefix: gastronomía, gastritis, gastrointestinal, gasterópodo.
