however, in the more formal speech, the contrast between oral and nasal vowels exists, as a result of the disfixing process on an ending nasal consonant.

in fact, the verbal agreement for 3>3 present forms of verbs do use a form of partial reduplication(prefixing the last consonant of the verb stem to the verb stem itself, when the verb stem is ended with a vowel, other rules are used(depending on whether the verb stem is ended with -e/-e: -o/-o: -a/-a: or -ra:), but they can be seen as variants of this partial reduplication rule) as well as the disfix of the last sound of the verb, an epenthetic vowel "i" may also be used in the reduplication process. for example, the present 3>3 form of the verb "nam"("to hold") is "mina", and the present 3>3 form of the verb "k-nam"("to hold") is "k-mina"(where the k- is a coverb, it is usually seperated from the stem and may take its own affixes in actual speech).

adpositions agree with the gender/class of the noun modifying them.

SOV/SVO, depending on the class of the object.

different objects use different word orders, but the word order for each object is fairy rigid and don't normally changed.

some words mainly use the OV order; other words mainly use the VO order

some adpositions are obliged to be postpositions, but other adpositions can be either prepositions or postpositions.

the analytical postposition "a" is used on core arguments, the usage of the postpostion "a" depends on the existence of volition and the animacy of the noun it modifies.

when the agent of a transitive verb is an inanimate object, or when the agent of any verb is an unvolitional animate object(i.e. lack of control over the action, performs the action without the existence of volition, etc.), the postposition "a" is used;

when the patient is an animate object, the postposition "a" may be used or may not be used;

in other situations, the postposition "a" is not used.

both of the Indirect-object construction and the Secondary-object construction can be used.

Internally-headed relative clause is the main type of relative clause used for relativizing core arguments.

doubly-headed relative clause is the main type of relative clause used for relativizing obliques.

in writing, more formal situations or situations where numbers do matter(e.g. science, technology, financial, etc.), a quadrivigesimal(base-24) numeral system is used instead.
