Etymology
the compound adjective 'high-carb' is a modern nutritional term formed within english. the first element, 'high', derives from the old english word 'hēah', meaning tall or lofty, which via proto-germanic and proto-indo-European roots relates to concepts of increase and large quantity. the second element, 'carb', is a 20th-century clipped form of 'carbohydrate', a scientific term itself formed from 'carbon' and 'hydrate'. the logic of the compound is transparently descriptive, combining the qualitative sense of 'high' meaning 'large in amount or degree' with the abbreviated form of the specific nutrient, 'carbohydrate', to efficiently denote a food rich in this macronutrient.
