querulous [ˈkwɛrələs]
adj
Someone described as querulous is constantly or habitually complaining. Querulous can also be used synonymously with fretful or whining when describing something, such as a person's tone of voice.
The Middle English form of the word, querelose, was an adaptation of the Latin adjective, querulus, which in turn evolved from the Latin verb queri, meaning "to complain."
