"Querulent" Natural Recordings by Native Speakers
Whining or complaining in a persistent and annoying manner.
A quern is an ancient tool for grinding grain into flour, typically consisting of two circular stones. It was used before the invention of mechanical mills and was often operated by hand.
I couldn't find any words in my dictionary that matches the spelling of "querquedule". However, a possible match could be "querulous" which is an adjective that means peevish, fretful, or irritable, often in a complaining or insulting way.
