Fussy meaning is reasonably hard to grasp. It refers to someone who is extremely choosy and critical. A
persnickety individual tends to be meticulous and sets the bar high when it comes to criteria and perfection. Their attention to detail can be perceived as commendable, but it can also exacerbate unwarranted censure and unjustified dissatisfaction. Being persnickety is regularly linked to precise focus on specifics but can also be seen as a form of obsessiveness.
