Persnickety meaning is rather elusive. It refers to someone who is exceptionally selective and fault-finding. A persnickety individual typically pay strict attention to detail and sets the bar high when it comes
to standards and excellence. Their fastidious nature can be seen as admirable, but it can also magnify unreasonable criticism and unnecessary dissatisfaction. Being persnickety is typically linked to precise attention to detail but can also be seen as a type of obsessiveness.
