Particular meaning is somewhat difficult to understand. It refers to someone who is exceedingly choosy and judgmental. A persnickety individual often nitpick
and does not settle for less when it comes to quality and
flawlessness. Their fastidious nature can be perceived as commendable, but it can also exacerbate unwarranted censure and unjustified dissatisfaction. Being persnickety is regularly associated with precise attention to detail but can
also be seen as a manifestation of pedantry.
