Just learnt that "Min Nan" dialect can be referred to "Hokkien"

[jpatokal]

"Hokkien" is an approximation of how "Fujian" is pronounced in Min Nan, which in turn means "Southern Min" (dialect/language).

Singaporeans and Malaysians almost always call the language "Hokkien" - at least when speaking English. "Min Nan" seems like a term only linguists use.
