Etymology

Origin of sweat

First recorded before 900; 1970–75 sweat for def. 6; (verb) Middle English sweten, Old English swǣtan “to sweat,” derivative of swāt (noun); (noun) Middle English swet, sweet, influenced by the verb, cognate with Dutch zweet, German Schweiss, Old Norse sveiti; akin to Sanskrit svéda-, Latin sūdor, Greek hidrṓs

Explanation

Sweat is perspiration that makes you feel cooler when it evaporates off the surface of your skin — or the giving-off of this liquid. If you exercise hard, you will sweat. The word sweat comes from the Old English word swætan, which means “perspire,” and “work hard.” Though sweat is the body's way of cooling itself, today it also means "to worry or be stressed out." If someone tells you not to sweat it, it means "don't worry." But if someone is "sweating" you, it means you are hassled, maybe being asked every five minutes, "Did you finish your work yet?"
