Persnickety meaning is reasonably hard to grasp. It refers to someone who is extremely selective and disapproving. A persnickety individual often be fastidious and sets the bar high when it comes to expectations and perfection. Their fastidious nature can be regarded as praiseworthy, but it can also magnify overly demanding censure and superfluous dissatisfaction. Being persnickety is commonly linked to exact focus on specifics but can also be seen as a type of obsessiveness.
