enthusiast

Someone deeply interested

An enthusiast is someone with intense interest or passion for a particular subject or activity: a car enthusiast, wine enthusiasts gathered for the tasting.

The word implies deep engagement beyond casual interest—enthusiasts collect, study, discuss, and advocate for their chosen pursuit.

It's often used attributively: enthusiast forums, enthusiast-grade equipment.
