Persnickety sense is somewhat elusive. It refers to someone who
is immensely particular and fault-finding. A persnickety individual tends to pay strict attention to detail and does not settle for less when it
comes to expectations and perfection. Their fastidious nature can be seen as admirable, but it can also exacerbate excessive criticism and superfluous dissatisfaction. Being persnickety is commonly related to precise attention to detail but can also be seen as a manifestation of obsessiveness.
