Choosy meaning is fairly hard to grasp. It refers to someone who is vitally meticulous and nitpicking. A persnickety individual tends to pay strict attention to detail and has high standards when it comes to quality and perfection. Their attention to detail can be seen as admirable, but it can also exacerbate excessive censure and avoidable dissatisfaction. Being persnickety is typically related to meticulous attention
to detail but can also be seen as a type of obsessiveness.
