at rest; calm; quiet
I go out for a walk by the lakeshore every dawn, because the countryside is so quiescent and peaceful at that time.
quies quietis (rest, quiet) (Latin)
quiz + cent, teacher asks students who will get cent (100) in the quiz. everyone reamains silent for sometime quiescent => quies ~ quiet = motionless quies (QUITE)+scent (in hindi shant means quite). so someone who is quite or shant for a period of time.
