Answer 2

There is no such word in English as bua. Your father's sister is your aunt, and the comon form of address for her is Auntie but sometimes Aunt is also used, followed by her first name: if your father's sister's name were Anne, she would be called Auntie or Aunt Anne. I hope that answers your question.
