To oppisite a word, we use in- and un- ..
for example , the oppsite of competent is incompetent , and ambitious is unambitious ..
Ok, when do I use in- and when do I use un- ?why dont we say uncompetent or inambitious ?
is there a grammatical rule for that ?
Happy - unhappy
Articulate - inarticulate
Proportionate - disproportionate
Clean - unclean
Appropriate - inappropriate
Typical - atypical
I suggest that each time you come across a new adjective, immediately look up the opposite and try to learn it at the same time.
