All non-syllabic consonants except [p̚, t̚, k̚] may begin a syllable, but some speakers don't have initial [n, ŋ].[6] The six non-syllabic consonants [p̚, t̚, k̚, m, n, ŋ] may end a syllable.[7]
^Non-syllabic initial [ŋ] is not pronounced in Hong Kong Cantonese by younger speakers, who replace it with a glottal stop [ʔ] before a, e, o. Also, initial [n] may be replaced by [l].
^Non-syllabic final [ŋ] may be replaced by [n] in Hong Kong Cantonese except after [e, o]. [i, u] in diphthongs are equivalent to a final /j, w/. After rounded vowels, an i becomes [y].
^Syllable-initial yu is [jo] before k or ng, and [jyː] otherwise.
^The high level and high falling tones have merged to high level in Hong Kong Cantonese for most words.
