Etymology
Origin of water
First recorded before 900; (for the noun) Middle English wæter, water, watre, Old English uæt(t)er, wæter; cognate with Dutch water, German Wasser, Old Norse vatn, vatr Gothic wato; akin to Hittite watar, Greek hýdōr, Irish uisce, Russian vodá; (for the verb) Middle English watere(n), Old English wæterian, wetrian “to give water to, irrigate, moisten,” derivative of the noun
Explanation
The liquid that is made up of two parts hydrogen and one part oxygen is water. Water takes up over seventy percent of the earth’s surface. Your body is made of about sixty percent water. Water can be a noun: it is the colorless, odorless liquid that all living things need to survive. Water can be a verb: as in watering the plants, getting teary, or urinating. When people talk about freezing and boiling, they are usually talking about the temperatures at which water freezes (32˚ F) and boils (212˚ F). Humans use water to bathe, cook, make fountains in the backyard, and mix with lemon juice and sugar to make lemonade.
