Persnickety sense is somewhat hard to grasp. It refers to someone who is exceptionally selective and disapproving. A persnickety individual tends to pay strict attention to detail and sets the bar high when it comes to quality and perfection. Their attention to detail can be regarded as praiseworthy, but it can also intensify unreasonable censure and unnecessary dissatisfaction. Being persnickety is regularly related to detailed focus on specifics but can also be seen as a type of perfectionism.
