Persnickety sense is reasonably elusive. It refers to someone who is exceptionally meticulous and fault-finding. A persnickety individual tends to pay strict attention to detail and does not settle for less when it comes to criteria and perfection. Their fastidious nature can be perceived as commendable, but it can also exacerbate extreme censure and unnecessary dissatisfaction. Being persnickety is typically associated with detailed focus on specifics but can also be seen as a type of perfectionism.
