Querulousness

ˈkwɛrjʊləsnəs

noun

the quality of being complaining or full of complaints

Querulousness describes a tendency to complain or grumble frequently and often about trivial matters. It is related to being constantly dissatisfied or irritable. This word is derived from the Latin word 'queri,' which means 'to complain.'

Princess Márya well knew this mood of quiet absorbed querulousness, which generally culminated in a burst of rage, and she went about all that morning as though facing a cocked and loaded gun and awaited the inevitable explosion.

Leo Tolstoy

War and Peace

He taunts Cervantes with being old, with having lost his hand, with having been in prison, with being poor, with being friendless, accuses him of envy of Lope's success, of petulance and querulousness, and so on; and it was in this that the sting lay.
