Particular meaning is somewhat hard to grasp. It refers to someone who is immensely picky and fault-finding. A persnickety individual tends to be meticulous and does not settle for less when it comes to expectations and perfection. Their meticulousness can be viewed as laudable, but it can also exacerbate excessive censure and superfluous dissatisfaction. Being persnickety is regularly related to precise attention to detail but can also be seen as a form of pedantry.
