I can't believe I'm an ESL teacher and I'm asking this question. What is an antonym for famous? Doesn't "infamous (pronounced IN-fa-mous) mean very famous? None of the other negating prefixes seem to work - "nonfamous, unfamous...". I'm thinking of just going with "unpopular". The question for my students is, "Make a list of the good things and bad things about being an __________ musician."
