Particular definition is somewhat tricky to comprehend. It refers to someone who is exceptionally choosy and critical. A persnickety individual tends to pay strict attention to detail and
has high standards when it comes to expectations and excellence. Their attention to detail can be viewed as laudable, but it can also exacerbate extreme censure and superfluous dissatisfaction. Being persnickety is typically linked to precise focus on specifics but can also be
seen as a form of obsessiveness.
