Subordinate clauses

Coordination joins equals. Subordination nests one thought inside another: a sentence becomes a component of a larger sentence, its object, its reason, its condition, or its context.

English handles this with words like "that," "because," "after," "although," and "whether." Phi does the same, but with a characteristic difference: the subordinating word always comes first and announces the relationship before the content arrives. The listener knows they're entering a subordinate clause the moment they hear the marker.

How subordination works in Phi

A subordinate clause is introduced by a complementizer or subordinating conjunction that announces its function. The clause then unfolds, and the main clause follows (or, in the case of complement clauses, the subordinate clause sits in the object position).

The general pattern for adverbial clauses:

[subordinator] [subordinate clause] [main clause]

lao shia to wepu mia phaelo.
BECAUSE 3SG PST go 1SG feel.
(Because they left I feel.)

The subordinator lao announces "here comes a reason." The reason unfolds (shia to wepu, "they left"). Then the main clause delivers what that reason explains (mia phaelo, "I feel").

For complement clauses, the embedded clause serves as the object of a verb. Complementizers that introduce these clauses come in pairs: an opener and a closer, which work like spoken parentheses around the embedded thought.

[subject] [complementizer] [embedded clause] [closer] [verb]

mia mena shia to wepu meno sano.
1SG DECL.COMP 3SG PST go DECL.COMP.CLOSE know.
(I know that they left.)

The complementizer mena announces "here comes an embedded statement." The closer meno marks where it ends. The main verb sano ("know") follows: it tells you what the speaker is doing with that statement. Without meno, the boundary between the embedded verb and the main verb would be ambiguous.

Both patterns follow the modifier-first principle: the relationship is announced before the content that fills it. The listener is never caught off guard by a clause's function.
