Persnickety sense is reasonably difficult to understand. It refers to someone who is exceptionally meticulous and critical. A persnickety individual tends to be fastidious and does not settle for less when it comes to quality and flawlessness. Their fastidious nature can be seen as admirable, but it can also magnify unreasonable disapproval and unnecessary dissatisfaction. Being persnickety is commonly related to exact focus on specifics but can also be seen as a type of perfectionism.
