Chapter 15 Voice and possibility
Necessity na
na presents a predicate as necessary. The source may be a bodily need, physical constraint, logical conclusion, practical requirement, or stated obligation.
mia na nulae. — I need to sleep.
womu ki se na lorima. — The house must have been built.
lo mia na naphe. — We must help.
The same particle covers these readings because each presents one course or conclusion as necessary. Context must say what creates that necessity and who accepts it.
Necessity and inference
na is a modal, not an evidential. A logical conclusion may also be inferred from specific evidence, in which case both ranks can appear:
womu ki se ke na lorima. — From the evidence, I infer that the house must have been built.
ke identifies inference as the claimed source. na states that the conclusion is judged necessary. Neither particle rates the evidence or guarantees the reasoning.
Necessity and power
In lo mia na naphe, grammar does not reveal who set the obligation, what circumstances support it, or whether anyone agrees. A physical need and an institutional demand can wear the same modal while having very different consequences.
This is where Phi's peace-linguistic practice belongs: not in pretending that na makes pressure reasonable, but in asking for the source, authority, alternatives, and effects when they matter. Those answers take ordinary nouns and clauses rather than another modal particle.

| Phi | English |
|---|---|
mia to na thalo. | I had to walk. |
thia so na shonela. | You will need to learn. |
mia si na thalo. | I must be walking. |
mia ki na kamo. | I must have arrived. |
Negation follows the modal. na ma means must not, the necessity of refraining. Absence of obligation is a different claim and uses the freedom construction in the next section.
na makes necessity audible. Whether necessity was discovered, negotiated, imposed, or merely asserted is still the question worth asking.
