Particular sense is rather difficult to understand. It refers to someone who is extremely selective and disapproving. A persnickety individual typically nitpick and does not settle for less when it comes to quality and flawlessness. Their fastidious nature can be regarded as praiseworthy, but it can also magnify unwarranted criticism and avoidable dissatisfaction. Being persnickety is frequently associated with detailed focus on specifics but can also be seen as a form of perfectionism.
