fussy

the word 'fussy' is a relatively modern english formation. its core, 'fuss', emerged in the 18th century, likely as an expressive, imitative word capturing the sound and agitation of unnecessary bustle or complaint. the addition of the productive adjectival suffix '-y', with its ancient germanic lineage tracing back to proto-germanic -īgaz and ultimately proto-indo-European -ikos, transformed the noun/verb into a descriptive term. the literal construction "full of fuss" logically evolved to describe a person who is excessively concerned with trivial details or an object overly adorned with finicky elements, perfectly capturing the modern senses of being hard to please or excessively ornate.

Structure: fuss (noun/verb) + y (adjective-forming suffix) fuss (origin uncertain, likely imitative of fussy sounds or actions; functional role: core semantic root) + y (from old english -ig, middle english -y; functional role: suffix forming adjectives meaning "characterized by, full of, or inclined to")
