A person who practices dilettantism; someone characterized by casual or superficial engagement in art, learning, or other pursuits.
From dilettante plus -ist suffix (meaning 'one who practices'). Parallel formations include 'artist,' 'scientist,' and 'pianist,' where -ist identifies the practitioner.
By adding -ist to dilettante, English speakers transformed a description of behavior into a social identity—you weren't just dabbling, you were a 'type of person,' a dilettantist!
