sweat

use of physical or mental energy; hard work

he got an A for effort

they managed only with great exertion

salty fluid secreted by sweat glands

sweat poured off his brow

condensation of moisture on a cold surface

the cold glasses were streaked with sweat

agitation resulting from active worry

don't get in a stew

he's in a sweat about exams

excrete perspiration through the pores in the skin

Exercise makes one sweat
