This diagram might help. http://langintro.com/kintro/family/unc_aunt.png I did miss a few possibilities as I should also have asked if the aunt married to a maternal uncle! Good luck!!

It isn't so simple... more information is needed. Is this your maternal aunt? Paternal aunt? If so, what birth ranking from other female siblings? Aunt who is married to a maternal uncle? Aunt who is married to a paternal uncle? If married to a paternal uncle, how what is this uncle's age ranked between his other male siblings including your father? Or is this "aunt" a close friend of the family particularly a close friend of you mother? Each one of the above questions have a different name for "aunt"... except for the first and last questions. The title here is the same. I hope I covered all of the possibities. I have the same problem as I must learn "aunt" and "uncle" in Persian which I have heard is similarly complicated.. but perhaps not quite a much as Korean is. :)

Thanks guys can guys tell me how to say that in Korean
