Choosy meaning is fairly hard to grasp. It refers to someone who is exceedingly selective and disapproving. A persnickety individual tends to be fastidious and has high standards when it comes to standards and excellence. Their attention to detail can be regarded as praiseworthy, but it can also magnify unwarranted criticism and superfluous dissatisfaction. Being persnickety is regularly linked to detailed attention to detail but can also be seen as a manifestation of obsessiveness.
