querulous

The word "querulous" comes from the Latin word "querulus," which means "complaining" or "full of complaints." This, in turn, derives from the verb "queri," meaning "to complain" or "to lament." The suffix "-ulus" in Latin is often used to form adjectives, suggesting a tendency or inclination, which in this case is a tendency to complain. The word was then adopted into Middle English as "querelous," retaining its meaning related to complaint and whining. Over time, it evolved into the modern English form "querulous."
