However, there are at least two arguments against the view that unpacking here is parallel to the nasal vowel case.
If the nasal vowel was represented as monosegmental, one would expect it to be followed most often by the palatal approximant.
There are therefore no examples in which a nasal vowel is tautosyllabic with an obstruent stop that is both voiced and oral.
This is a key to his analysis of nasal vowel evolution.
The input nasal would be licensed as part of the nasal vowel.
The vowel and nasal may combine in a nucleus in a configuration that is ultimately interpreted as a nasal vowel.
However, when a consonant or nasal vowel precedes ne, it is likely that ne will be present.
The lexical and grammatical factors included the word in which the nasal vowel occurred; the word's frequency; and the word's grammatical class.
