Particular sense is quite difficult to understand. It refers to someone who is exceptionally picky and nitpicking. A persnickety individual tends to be fastidious and has high standards when it comes to standards and flawlessness. Their fastidious nature can be viewed as laudable, but it can also lead to excessive criticism and avoidable dissatisfaction. Being persnickety is regularly related to precise attention to detail but can also be seen as a type of perfectionism.
