Etymology
Origin of quiescent
First recorded in 1600–10; from Latin quiēscent- (stem of quiēscēns, present participle of quiēscere ), equivalent to qui-, base meaning “rest, quiet” + -ēsc- inchoative suffix + -ent- -ent
Explanation
The adjective quiescent means "being quiet and still," like the quiescent moments lying in a hammock on a beautiful summer Sunday. To be quiescent, pronounced "qwhy-ESS-ent," is to be quiet, resting, which is exactly what its Latin origin quiescens means: In our busy world, it is hard to find a place to be quiescent. It has a second meaning: "causing no symptoms." For example, if a disease is quiescent, you probably won't know you have it. And finally, quiescent can mean "not activated," like quiescent cleaning products that don't get the stains out.
