Combining tense and aspect
Tense and aspect particles can combine to create precise temporal meanings. In Phi's strict ordering, tense precedes aspect: tense > aspect > voice > evidentiality > modality > negation.
The combination system
When tense particles combine with aspect particles, they create nuanced descriptions of how events unfold through time.
| Combination | Gloss | Meaning |
|---|---|---|
| to si | PST IPFV | was doing (ongoing in the past) |
| to ki | PST PFV | had completed (finished in the past) |
| to pa | PST INCH | began (started in the past) |
| to te | PST CESS | stopped doing (ceased in the past) |
| to ro | PST HAB | used to do (past habit) |
| so si | FUT IPFV | will be doing (ongoing in the future) |
| so ki | FUT PFV | will have completed |
| so pa | FUT INCH | will begin |
| so te | FUT CESS | will stop doing |
| so ro | FUT HAB | will habitually do |
Examples in context
Past progressive (to si):
mia to si theo
"I was reading."
This marks an action that was ongoing at some past moment. The event is placed in the past with to, and its unfinished, flowing quality is captured by si.
Past perfective (to ki):
mia peloru to ki nila
"I had seen the flower."
This marks an action completed before another past reference point. The past tense to locates the event, while perfective ki emphasizes its bounded completeness.
Future inchoative (so pa):
thia so pa theo
"You will begin to read."
This projects the inception of an action into the future. The future so establishes when, while inchoative pa focuses on the moment of beginning.
Past habitual (to ro):
mia to ro meliho
"I used to sing."
This describes a pattern of repeated action in the past. The habit existed then but no longer continues into the present.
Unmarked forms
Remember that both present tense and neutral aspect are unmarked in Phi. The verb alone, without particles, expresses present tense with neutral aspect:
mia theo
"I read."
This could describe reading happening now, or express a general truth about the speaker's reading ability. Context determines the interpretation.
The complete palette
Together, tense and aspect particles provide a precise vocabulary for temporal expression. By requiring explicit marking, Phi ensures that every statement about action becomes a moment of reflection about the nature of time itself.
The present remains the foundation. Every departure into past or future requires conscious choice. And within each temporal location, aspect particles reveal whether we view the action from inside its flow, at its boundaries, or across its repetitions.
