On Java, you can call people close to you or teachers tante. (If they're female of course)
Yeah and I have been called "om" by people many times in Bali. "Om" is uncle, by the way.
Paman saya adalah suami bibi saya
Om saya adalah suami tante saya
In Turkish we have 3 words each for uncle and aunt. One for paternal, one for maternal, and like in this case one for uncle/aunt by marriage.
