petty 【PETTY】The children's quarrels usually concern a petty problem.小孩子们争吵常常只是因为琐细的问题。【重点词汇】petty adj. 细小的 反: significant

Accepted Answer

['peti] 
petty(informal) small and of little importance
Petty used to mean just "petite" or "small," but now it's used for things that are trivial and shouldn’t matter much. If you host world leaders and spend more time picking napkins than memorizing names, you're focused on petty things.
A few neutral meanings of petty are still in use today — such as "petty cash," which refers to a small amount of cash on hand — but most uses of petty since the 16th century are negative, as in "narrow-minded," "trivial," and "of little importance." A "petty argument" is a popular expression, because many people get all worked up over something that isn't very important — a petty concern — that seems much smaller after the heat of the moment.
