Persnickety Definition Meaning Fussy definition is quite elusive. It refers to someone who is exceptionally choosy and disapproving. A persnickety individual tends to nitpick and does not settle for less when it comes to quality and flawlessness. Their meticulousness can be perceived as commendable, but it can also exacerbate extreme censure and superfluous dissatisfaction. Being persnickety is typically connected with detailed focus on specifics but can also
be seen as a type of obsessiveness.
