KK: /ˈflaʊərɪʃər/
A person who grows or develops successfully, often in a thriving or prosperous way.
The artist became a flourisher in the local art scene, gaining recognition for her unique style.
Flourisher → It is formed from "flourish" (from Old French *florir*, meaning to bloom or thrive) and "-er" (meaning a person who). A flourisher is a person who thrives or blooms in a particular context.
Think of someone who is 'blooming' or 'thriving' — that's what a flourisher does, and the '-er' just means a person.
