MDBG and Baidu provide a pronunciation of 咯 (as in the sentence-final particle indicating that something is obvious) as lo5. "lo" isn't listed on Wikipedia's pinyin table, and I thought only bo/po/mo/fo could drop the u from -uo. Is this the standard pinyin? Is "lo" pronounced the same as "luo"?

  • I think the final particle "lo" is probably not native Mandarin, and is probably borrowed from 囉 in Cantonese or other southern Chinese languages.

According to yabla, 'Io' is a valid pinyin. Quoting yabla:

咯 luò

to cough up

咯 lo

(final particle similar to 了, indicating that sth is obvious)

咯 gē



Example Usage just for that middle one(from yabla):



English: Ha ha ha ha! We are back. -You are back. You are back.


A pinyin table from allsetlearning:

pinyin table

That proves to me that lo is a valid pinyin.

  • Come to think of it, the Wikipedia table is also missing o, which is a pretty big omission.

  • @MiCl no it isn’t, o is the very first row/column entry. ø- (first row) is a None initial, so øo is o.

    @droooze oh yeah, I edited the Wikipedia article after I posted that comment to add an -o row, so now it has o and lo
