Complaining in a rather petulant or whining manner: Inclined to make whining or peevish complaints.
It is the manner in which the complaint is being made that is the deciding factor as to whether someone is merely complaining or querulous with the latter being marked by a high pitched whining tone.
“His urbanely crinkly face oozes disapproval; his querulous voice is like a fingernail at a scab.”
“The querulous critic who scolds it as he would a spoiled child, has not learned the primer of politics..”
Originally: a bald head; a bald-headed person. In later use also: a pitiable, lowly, or foolish person; a shabby or unkempt person. Frequently used without article, as though a proper name.
Early 16th century; earliest use found in John Skelton (c1460–1529), poet. In some forms apparently partly from pilled + garlic and partly from peeled + garlic; in some forms apparently partly from pill + garlic and partly from peel + garlic.
