Classification 
Mori Bawah is classified as a member of the Bungku-Tolaki group of languages, and shares its closest affinities with Bungku and other languages of the eastern seaboard of Sulawesi, such as Wawonii and Kulisusu.  Together, Mori Bawah and the Mori Atas language are sometimes referred to collectively by the cover term Mori.

Grammar

Pronouns 
Mori Bawah has seven sets of bound and free pronouns:

Agreement 
Core arguments (A: subject of transitive verbs;  O: object of transitive verbs, S: subject of intransitive verbs) are not marked for case, but are obligatorily indexed by a pronominal agreement marker on the verb.

With transitive verbs, A is always indexed by a nominative pronoun, and O by an absolutive pronoun.

The indexing of the single argument of intransitive verbs shows split-ergative alignment: S is always indexed by a nominative pronoun in future clauses, and also in imperative, negative and certain other dependent types of non-future clauses. In all other cases, S is indexed by an absolutive pronoun.

Voice 
Mori Bawah has two valency-reducing voice types, passive voice and antipassive voice.

If a transitive verb is marked for passive voice with the infix <in>, it becomes formally intransitive, and O (the "object") becomes the S-argument. The original A-argument cannot be mentioned at all.

In antipassive voice, the verb takes the prefix poN-. The object can be omitted, or overtly expressed if indefinite; it is however not indexed by a person-indexing pronoun. The original subject of the transitive verb becomes the S-argument in a formally intransitive antipassive clause.
