Cantonese has 2 syllabic nasals, namely /m ng/. These two finals occur in Putonghua, though only marginally as interjections or onomatopoeic words. As for English, there are interjections like ‘mm’ or ‘hmm’, but nothing like Cantonese /ng/.
There is mainly only 1 word under the /m/ final, namely ‘唔’. There are more words under the /ng/ final,
Cantonese speakers of younger generations pronounce /ng/ like /m/. For more, see ‘Language Change in Cantonese – /ng/ Pronounced Like /m/’.
