Discourse flow

Conjunctions connect elements within a sentence or join two sentences together. Discourse markers do something different: they connect a sentence to everything that came before it. They tell the listener how to relate what they're about to hear to what they've already heard.

English does this informally. "So," "however," "for example," "in other words": these are road signs in a conversation that orient the listener before the next idea arrives. Phi formalizes these into a small, consistent set of discourse markers with a fixed syntactic position.

Position in the sentence

All discourse markers occupy the same slot: after any Slot 0 particle but before the subject. This means they sit at the very front of the sentence (or just after wa, pi, no, etc.) and announce the logical relationship before any content arrives.

The pattern is: [Slot 0] [discourse marker] [subject] ... [verb]

mia shea phaelo. thelao mia thesua nai.
1SG peace feel. CONS 1SG mindful be.
(I feel peace. Therefore I am mindful.)

mia shea phaelo. whekai mia thesua ma nai.
1SG peace feel. CONTR 1SG mindful NEG be.
(I feel peace. However I am not mindful.)

Notice the discourse marker comes before mia in the second sentence. The listener hears thelao or whekai and immediately knows whether the next thought will build on the previous one or push back against it. Context before content.

How discourse markers differ from conjunctions

Conjunctions (nela, thona, sola) join grammatical equals: two nouns, two clauses, two phrases. They operate within the sentence structure.

Discourse markers operate between sentences. They don't join grammatical elements; they signal how the speaker's thinking is moving. A conjunction says "these two things go together." A discourse marker says "here's how what I'm about to say relates to what I just said."

This distinction matters in practice. You would never use thelao to join two nouns, and you would never use nela to connect two independent lines of reasoning across a paragraph.

Phi has seven discourse markers. They cover the most common logical moves in conversation: drawing conclusions, redirecting, adding support, illustrating, rephrasing, narrowing focus, and summarizing. The sections that follow cover them in functional pairs.
