The combining form hydr/o denotes which substance?

Explanation:
Hydr/o denotes water. In medical terms, combining forms link a root to a suffix or another element, and hydr/o is used whenever the word relates to water. That’s why hydration means giving or retaining water, while dehydration means loss of water. Other substances use different roots (oxygen with oxy- or ox-, glucose with gluc- or glyco-, minerals with mineral-), so hydr/o is specifically about water.
