The following dialects are distinguished in Ethnologue.Northern dialect: particularly the Gunungsitoli variety, Alasa and Lahewa area.
South dialect: South Nias, Gomo Area, Telukdalam Area and Batu Islands
Central dialect: Sirombu and Mandrehe areas, particularly in West Nias.
The southern dialect of Nias has the following phonemes:
The status of initial [ʔ] is not determined; there are no phonetic vowel-initial words in Nias. Northern Nias has /ŋ/ but not /c/; in addition, /z/ is pronounced [z].
Nias has an ergative–absolutive alignment. Unusually, it appears to be the absolutive (mutated) case which is marked, against the near-universal tendency to mark the ergative.
There are no adjectives in Nias, with that function taken by verbs.
Nias shows consonant mutation at the beginning of nouns and some other classes of words to show grammatical case. Several consonants are subject to mutation as shown in the table below. Where a word begins in a vowel, either n or g is added before the vowel; the choice of n or g is lexically conditioned. (For example, öri ~ nöri is 'village federation', öri ~ göri is 'bracelet'.)
Other consonants do not change.
The unmutated form is used in citation. The mutated form only occurs on the first noun in a noun phrase (that is, not after a conjunction like 'and'). It is used for:absolutive case (with a transitive verb, only in a main clause; with an intransitive verb, also in dependent clauses)
possessor (nouns only; pronouns take a genitive case)
object of most prepositions (pronouns take the genitive)
both arguments of some experiencer verbs, such as:
'The monkey is afraid of the child'
Besides being the citation form, the unmutated form is used for:ergative case
both arguments (A and P) in a dependent transitive clause
predicate nominal (with a copula)
with löna 'to not exist'
after some prepositions (such as faoma 'with (instrumental)')
