The word "petty" refers to something that is of little importance or significance. It often describes minor issues, trivial matters, or behaviors that are small-minded or insignificant. People who are described as petty may focus on small faults or grievances rather than considering the bigger picture.
"Petty" comes from the Middle English word "petit," which originated from the Old French word "petit" meaning "small" or "little." This, in turn, traces back to Latin "pittīnus," which relates to the term "pictus," meaning "painted" or "small."
