Person

Bornidalgian verbs have two three paradigms: intransitive verbs, which do not show agreement, and transitive verbs, which have double agreement, with the subject and the direct complement. In the first case, the arguments are those that manifest the endings of name and person. For example: walei nkawan (“we have slept”). In the second, the arguments only receive ergative or accusative marks, while it is the verb that expresses the person and the number. For example: uponleidan nkaǰ suing  (“we ate apples”). The personal suffixes are the following:

ergative prefixes: ky- (1st exclusive), u- (1st inclusive), ma- (2nd), no prefix (3rd)

ergative number suffixes: -y- (dual) and -d(a)- (plural)

accusative suffixes: -kyla- (1st exclusive), -wa- (1st inclusive), mur- (2nd), no suffix (3rd),

accusative number suffixes: -ka (dual) and -n (plural)

Tenses

Bornidalgian has four tenses, which are formed with a suffix postposed to the root. These are, respectively, -ri (present), -lei (perfect), -neu (anterior relative) and -ngo (posterior relative). The relative anterior and posterior are tenses that are built in relation to others. For example, in nkakyla walei kyponneu, (“I went to sleep after I ate”) kyponneu is constructed as a time after walei.

Mood

In Bornidalgian there are six verbal moods, with their respective suffixes, which are located after the tense suffix: indicative (without suffix), evidential (-ky-t-, -u-t- and -ma-t-), negative (-o -), doubtful (-kia-), interrogative (-gol-) and participle (see below). The evidential mood is manifested with three groups of suffixes, composed of the ergative prefixes and the mood suffix -t-. uponrikytd (“according to me/we (1-3), we have eaten an apple”), uponriutd (“according to me/we (1-2-(3)), we have eaten an apple”), uponrimatd (“according to you, we have eaten an apple"). Participles are formed by adding to the tense stem (root and tense suffix) a voice prefix (ma-, antipassive, and bo-, passive) and nominal morphemes. For example, the spirit name bomakuri is the passive participle of the verb makuǰai, “to invoke.”

Voice

The participles are marked with the aforementioned morphemes. The conjugated forms are marked with the suffix -par, for the passive voice, and -mog, for the antipassive voice. Both the agent and passive complements are constructed as an ablative complement, when it is a conjugated form, and as an indirect genitive complement, when it is a participle.

ponri ierǰa lunnga, "the bear eats the child"

ponripar lun womier, "the boy is eaten by a bear" (passive sentence)

niier boponri lun, "the boy is eaten by a bear" (passive participle)

ponrimog ier womlun, "the bear is the devourer of a child" (antipassive sentence)

nilun maponri ier, "the bear the devourer of a child" (antipassive participle)

The order of verbal morphemes is

Erg. Pref.-Root-Tens. Suff.-Mood. Suff.-Erg. No. Suff.-Accus. Suff.-Acus. No. Suf.
