"Naon" is Sundanese (use in East Java) means "What", "Opo" is Javanese (use in Central and West Java) also means "What". ^_^

'naon' is sunda language (bandung, west java) its means 'what?' in english

So "naon" is Sudanese? Is "opo" also same as "what"?

FYI, it's not Javanese. It's Sundanese. :)

in english naon has a same meaning with "what"
