dilettante (n.)

1733, "an admirer of a fine art, literature, science, etc., one who cultivates an art or literature casually and for amusement," a borrowing of Italian dilettante "lover of music or painting," from dilettare "to delight," from Latin delectare "to allure, delight, charm, please," frequentative of delicere "entice" (see delicious). Originally without negative connotation, "devoted amateur;" the pejorative sense "superficial and affected dabbler" emerged late 18c. by contrast with professional.
