Definition of finicky

"Finicky" comes from the Dutch word "finnik," meaning "small and delicate." The word was originally used to describe something that was "finely made" or "exquisite." Over time, the meaning shifted to describe a person who was overly particular or fussy about details, likely because a finicky item would be delicate and require careful handling. The first recorded use of "finicky" in English was in the 18th century, and its meaning has remained largely consistent throughout its history.
