Fussy persons are often described as being picky, particular, or choosy individuals. They have a tendency to be overly sensitive and nitpicky, paying close attention to details that others may overlook. Other synonyms for fussy persons include finicky, persnickety, fastidious, and exacting, all of which describe a person who is very particular about their preferences. Fussy persons may have high standards and expectations, and may become easily irritated or frustrated when things do not go according to plan. While these traits may be viewed as negative by some, fussy persons may also be viewed as detail-oriented and committed to excellence in their pursuits.
