Demanding meaning is reasonably hard to grasp. It refers to someone who is extremely particular and judgmental. A persnickety individual usually pay strict attention to detail and has high standards when it comes to standards and perfection. Their meticulousness can be seen as admirable, but it can also intensify excessive censure and unjustified dissatisfaction. Being persnickety is typically associated with exact focus on specifics but can also be seen as a form of pedantry.
