To produce an opposite meaning of a word, we usually add a prefix to it or use a totally different word (e.g. pretty/ugly).
Common prefixes include: un- (happy, unhappy), im- (possible/impossible), il- (legitimate/illegitimate), in- (effective/ineffective), ir- (regular/irregular), dis- (infect/disinfect), non- (metalic/non-metalic), and mis- (inform/misinform).
