What does fussy mean?
"Fussy" is an informal English adjective describing someone who is overly concerned with small details, particular to the point of being difficult to please, or prone to needless agitation over trivia. A fussy person might reject a perfectly good meal because the sauce touched the peas, or fuss endlessly over the alignment of picture frames. The word carries a mildly critical connotation, yet it is often used fondly rather than harshly — a "fussy eater" or a "fussy baby" evokes patience more than blame. In British English it also commonly suggests restless, fluttering worry, as in a fussy old gentleman who frets about the weather. Derived from the noun "fuss" — itself a word of debated origin, possibly Scandinavian — "fussy" entered common use in the eighteenth century and remains firmly embedded in everyday language, its derivatives including "fussily," "fussiness," and the colorful "fussbudget."

"Fussy" descends from "fuss," a word whose very origin is disputed — some scholars point to Old Norse, making your picky eater's complaint possibly a Viking inheritance.

Etymology of fussy
"Fussy" derives from "fuss," a noun first recorded in English in the late seventeenth century meaning a show of needless agitation or bustle. The origin of "fuss" itself has never been definitively established; theories trace it to Old Norse "fuss" (an agitated or heedless person) and to related terms in Danish and other North Sea languages. By the mid-eighteenth century, "fussy" had emerged as its adjective derivative, inheriting the sense of petty, restless concern over trifles.
