Tense, aspect, mood, and evidentiality in Òtpoetti̖ are spread throughout affixes and adverb phrases. TAM cannot be marked with a single particle. If there is no adverb to include in a TAM-marking adverb phrase, TAM is mostly (that is, with the exception of affixes) left up to context.
Derivational Aspect Affixes
These affixes are obligatory for a verb and take on a more lexical meaning than adverb particles do. They moreso express the degree of relevance of parts of the action. As such, these affixed are termed as denoting aspect-focus, rather than aspect. A verb may be marked as "stative-focused" with an affix, it can be grammatically non-stative due to a TAM adverb phrase.
n- marks stative-focused verbs (initial consonants of verbalized roots are deleted)
Verb root: napta̗’ (“to stay”)
Noun root: ubì (“eye”) >> nubì (“to see”)
(ō-) marks progressive-focused verbs (the affix is included if attached to a verbalized root; on verb roots there is no affix, but the initial vowel always has a high tone)
Verb root: āpta̗’ (“to stick around”)
Noun root: ubì (“eye”) >> ōübì (“to watch”)
v- marks inchoative-focused verbs (initial conosnants of verbalized roots are deleted)
Verb root: vapta̗’ (“to resist leaving”)
Noun root: ubì (“eye”) >> vubì (“to start to see”)
kk(à)- marks habitual-focused, gnomic-focused, or "propertative-focused" verbs, propertative meaning the action occuring is some property of the topic (the affix ends in a vowel if the following stem starts with a consonant)
Verb root: kkapta̗’ (“to hang around”)
Noun root: ubì (“eye”) >> kkubì (“to be that which sees”)
Grammatical Aspect Affixes
These affixes are obligatory as well, but are not derivational. They may only be unmarked when a verb is non-momentane and ambitelic. Ambitelicity can be marked with an evidential adverb phrase headed by the qo̱ particle.
-a̱ marks momentane verbs
TAME is expressed primarily through adverb phrases combining an adverb particle and word or clause that functions as an adverb in this position. The adverb particles mark the relationship that word or clause has to the main verb.
Tense is marked with specific times or relations to specific events.
The main verb and adverb will be shortened to MV and Adv, respectively).
Simultaneous particle: ngō (“while”; marks the MV and Adv as happening at the same time)
k’omo̖ (“today”; noun)
ngō k’omo̖ (“today”; adverb)
Previous particle: kâi (“before”; marks the MV as happening before the Adv)
kâi k’omo̖ (“yesterday”; adverb)
Subsequent particle: e̗ (“after”; marks the MV as happening after the Adv)
e̗ k’omo̖ (“tomorrow”; adverb)
Preparative particle: āno̖ (“for”; marks the MV as happening in order to prepare for the Adv)
āno̖ k’omo̖ (“for today”)
Causative particle: lite̱’ (“because”; marks the MV as the cause of the Adv)
lite̱’ k’omo̖ (“because of today”)
Productive particle: mu̗h (“from”; marks the MV as happening according to or created from the Adv; this can be used to form evidentials if the adverb is a source of information; usually the root is a noun for formation and a verb for evidentials)
mu̗h k’omo̖ (“from today”)
ōubì (“to watch”)
mu̗h ōubìi (“from observation”)
Cooperative particle: txo (“along with”; marks the MV as happening in cooperation or mutual contribution with the Adv)
txo k’omo̖ (“along with today”)
Partitive particle: mæ̖n (“including”; marks the MV as a whole that the Adv is a part of)
mæ̂n k’omo̖ (“including today”)
Brevitic particle: qo̱ (“during”; marks the MV as happening simultaneously, but only briefly relative to a longer lasting event denoted by the Adv)
qo̱ k’omo̖ (“during today”)
Contrastive particle: fui̱ (“or”; marks the Adv as an alternative to the MV; can be used for various epistemic moods)
otkèh (“there is not”)
fui̱ otkèh (“or not”) - used for potentials or speculatives
ttè (shortened version of òtpoettè (“to say”) for this usage)
fui̱ ttè (“or say”) - used for requesting verification of the statement (interrogative-dubitative)
maahyè (“there is”)
fui̱ maahyè (“or there is”) - used for hypotheticals
Some adverb particles can be combined with each other producing a compound phrase head, sometimes with a unique meaning compared to the component particles.
kâi ngō, the previous and simultenous particles together form a true inchoative aspect, distinct from the inchoative-focus of the derivational affixes.
āno̖ mu̗h, the preparative and productive particles together form a imperative or necessitative mood with the adverb being the reason (which one it is depends on context).
lite̱’ mu̗h, the causative and productive particles together form a deductive mood with the adverb being the reasoning.
kâi fui̱ otkèh, the previous and contrastive particles with the “there is not” adverb form a hortative or propositive mood (which one it is depends on context).
If an adverb phrase modifies an adverb rather than a verb, it is placed after it and initiated with the particle ge̱h.
