Demanding meaning is somewhat difficult to understand. It refers to someone who is exceptionally picky and nitpicking. A persnickety individual frequently pay strict attention to detail and sets the bar high when it comes to standards and perfection. Their attention to detail can be viewed as laudable, but it can also magnify unreasonable censure and unnecessary dissatisfaction. Being persnickety is often linked to exact attention to detail but can also be seen as a form of perfectionism.
