carbohydrate

Definitions

carbo- (carbon) + hydr (water) + -ate = 'carbon combined with water.' Early chemists found that sugars contain hydrogen and oxygen in the same 2:1 ratio as water (H2O), so they named the class 'watered carbon' — even though eating carbs has nothing to do with drinking water.
