puntiglio
Puntiglio is an Italian word that translates to "quibble," "nitpick," or "cavil" in English. It refers to a minor, often insignificant, detail or objection that is raised in an argument or discussion. Someone exhibiting puntiglio tends to focus on small points of contention, sometimes to the detriment of the larger issue at hand. It can be seen as a form of pedantry, where the exact meaning of words or the precision of details is emphasized excessively.
The term often carries a slightly negative connotation, suggesting that the person is being overly argumentative
