Consonant Mutation - Central Vanuatu Languages

Central Vanuatu Languages

Mutation of the initial consonant of verbs is a characteristic feature of many Austronesian languages spoken in central Vanuatu.

For example, in Raga language:

nan vano "I went"
nam bano "I go"

These patterns of mutations probably arose when a nasal prefix, used to indicate realis mood, became combined with the initial consonant of the verb. The possible ancestral pattern of mutation, and its descendants in some modern Central Vanuatu languages, are shown below:

Proto-Central Vanuatu *k > *ŋk *r > *nr *p > *mp
Raga (Pentecost) x > ŋg t > d v / vw > b / bw
northern Apma (Pentecost) k > ŋg t > d v / w > b / bw
southern Apma (Pentecost) v / w > b / bw
Ske (Pentecost) z > d v / vw > b / bw
Lonwolwol (Ambrym) r > rV ∅ > bV
Southeast Ambrym x / h / ∅ > g t > d v / h > b
northern Paama ∅ > k t > r
central/southern Paama k / ∅ > g / ŋ t / r > d
Nāti (Malekula) k / ʔ > ŋk t / r > nt / ntr v / w > mp / mpw
Maii (Epi) t > d v > b
Lewo (Epi) v / w > p / pw
Lamenu (Epi) ∅ > p
Bierebo (Epi) k > ŋk t / c > nd / nj v / w > p / pw
Baki (Epi) c > s v > mb

Nakanamanga (Efaté-Shepherds) k > ŋ r > t v / w > p / pw

Famous quotes containing the words central and/or languages:

    The fantasies inspired by TB in the last century, by cancer now, are responses to a disease thought to be intractable and capricious—that is, a disease not understood—in an era in which medicine’s central premise is that all diseases can be cured.
    Susan Sontag (b. 1933)

    No doubt, to a man of sense, travel offers advantages. As many languages as he has, as many friends, as many arts and trades, so many times is he a man. A foreign country is a point of comparison, wherefrom to judge his own.
    Ralph Waldo Emerson (1803–1882)
