🎉🙌 en-THOO-see-AST-a: the Greek 'en theos' = god within, so inspired and fired up
Entusiasta comes from Greek 'enthousiastes', built from en (in) + theos (god): someone possessed by a god. Spanish keeps the 'god-inspired' sense as an eager fan or enthusiast, and the same form works as an adjective.
