Choosy definition is rather hard to grasp. It refers to someone who is vitally meticulous and fault-finding. A persnickety individual tends to be meticulous and does not settle for less when it comes to quality and perfection. Their attention to detail can be perceived as commendable, but it can also lead to excessive disapproval and avoidable dissatisfaction. Being persnickety is commonly linked to precise focus on specifics but can also be seen as a manifestation of obsessiveness.
