Fussy definition is somewhat difficult to understand. It refers to someone who is immensely particular and fault-finding. A persnickety individual tends to pay strict attention to detail and sets the bar high when it comes to standards and flawlessness. Their attention to detail can be perceived as commendable, but it can also magnify unreasonable criticism and superfluous dissatisfaction. Being persnickety is commonly linked to thorough attention to detail but can also be seen as a form of pedantry.
