Question about Punctuation I looked into “huh” on the dictionary, and I found it is written like this. 1) “a grunt articulated as a syllabic m, or n with a voiceless onset, or as the syllable ˈhə, or ˈhəⁿ, often ending in a glottal stop, and uttered with a range of intonations, often read as ˈhə” But I thought it’s too many punctuation and this one would be more better to understanding. 2) “a grunt articulated as a syllabic m or n with a voiceless onset, or as the syllable ˈhə or ˈhəⁿ, often ending in a glottal stop, and uttered with a range of intonations, often read as ˈhə” So this is my question. Why is commas before “syllabic m” and “syllable ˈhə” needed?
