Pronunciation note: Whether the fronting extends to the nasal-coda rime is less clearly attested than for the open rime. Verify before citing. No source located: Wikipedia's fronting list covers the nasalised-vowel rime (ĩõ) and the checked rime (ioʔ), not a true nasal-CODA rime like this one, and Learn Teochew's regional-differences section explicitly says it does not address codas at all. This value is an editorial extrapolation from the attested open-rime pattern, not independently sourced.
