Part 5
The clause commas
English uses commas at several kinds of clause boundary. Phi has no single clause-comma word. Each construction marks its own structure:
| Construction | Audible or visible boundary |
|---|---|
| realis or irrealis condition | lu or lu he, followed by a complete sentence and its period |
| adverbial dependent frame | pheo, phoe, whau, lao, shai, or lila before the dependent clause; its final predicate completes the frame |
| embedded complement | matched tha ... tho, pha ... pho, or sha ... sho |
| coordination | nela, thona, or sola between equal constituents |
| list | nela at every boundary |
01Conditions take a period
lu thia naphe. mia towe phaelo.
COND 2SG help. 1SG well feel.
The condition is one complete sentence and the consequence is another. English often writes a comma between them; Phi uses its one visible mark.
02Dependent frames come first
Each adverbial relator introduces material that modifies the main clause, so the complete dependent frame precedes it:
pheo mia to theo mia shea phaelo.
POST 1SG PST read 1SG peace feel.
lila mia shonela mia theo.
PURP 1SG learn 1SG read.
In the first sentence, pheo opens the earlier event and theo completes it before the main subject mia arrives. The purpose clause follows the same modifier-first rule: lila mia shonela comes before the reading it explains. No adverbial clause may move behind the main clause.
03Complement frames have closers
mia tha shia to wepu tho sano.
1SG DECL.COMP 3SG PST go DECL.COMP.CLOSE know.
tha opens the proposition known, and required tho closes it before the outer sano. The closer, rather than a pause, tells the listener where the embedded material ends.
04Conjunctions stand between equals
sileta sulae nai nela howeli phaelu nai.
sun warm be COORD wind peaceful be.
The first predicate completes its clause, nela joins it to an equal clause, and the period waits until the coordination is complete. thona does the same structural work while marking contrast, and sola offers an alternative.
Lists repeat nela at every join:
shiro nela peloru nela whelina.
tree COORD flower COORD grass.
This repeated conjunction makes the grouping audible without importing English's choice between a serial comma and no serial comma.
05The splice that cannot happen
English's commonest punctuation error is the comma splice, two sentences joined by a mark too weak to hold them. Phi cannot commit it. Between two clauses there is either the full period or an audible conjunction, and nothing weaker exists to misuse. The semicolon, English's licensed splice, gets its own reckoning in Part 8.
Practicelocate the boundaries
For each line, locate the dependent frame, complement closer, conjunction, or sentence boundary. Explain which word or period makes it recoverable.
1. lao pheralu to nai lo peloru thuroa. 2. mia pha shia to wepu pho phaelo. 3. mia theo nela thia sheluo. 4. lu pheralu lepa. lo mia mua womu meilo.
Answers: 1. lao opens the reason, and the dependent predicate nai completes it before the main clause begins. 2. pha opens the embedded yes-or-no question and pho closes it before phaelo. 3. nela joins two complete clauses after theo. 4. lu opens the condition, and its period separates it from the consequence.
