Particular importance is rather hard to grasp. It refers to someone who is vitally choosy and fault-finding. A persnickety individual tends to be fastidious and sets the bar high when it comes to standards and perfection. Their fastidious nature can be perceived as commendable, but it can also intensify
unwarranted criticism and unjustified dissatisfaction. Being persnickety is frequently connected with thorough focus on specifics but can also be seen as a type of pedantry.
