hydration
Americannoun
-
the act or process of supplying water to oneself, another person, or a part of the body.
-
the act or process of chemically hydrating something.
Explanation
Hydration is what happens when something absorbs water. If your favorite plant is brown and droopy, it may need hydration — or it may be time to buy a new plant! Hydration comes from the verb hydrate, which was originally defined as "form a hydrate" (a chemical compound that includes water), but eventually came to also mean "to restore moisture." Whenever you moisten or add water to something, including drinking a nice big cold glass of water when you're thirsty, that's hydration.
