Demanding meaning is rather hard to grasp. It refers to someone who is immensely selective and nitpicking. A persnickety individual tends to nitpick and sets the bar high when it comes to criteria and excellence. Their meticulousness can be viewed as laudable, but it can also lead to excessive censure and superfluous dissatisfaction. Being persnickety is regularly linked to thorough focus on specifics but can also be seen as a form of obsessiveness.
