Triadic Grammar.

The one-sentence version

The triadic grammar names the logical minimum for meaning: you need a thing, a representation of that thing, and an interpreter capable of reading the representation as about the thing. Dyads are insufficient for semantics.

Where the term comes from

Peirce’s semiotics provides the foundational distinction between dyadic (stimulus-response) and triadic (sign-object-interpreter) relations. Ontogony argues that the symbolic exit occurs when a system offloads its interpretive work—when what was once accomplished by a living organism gets delegated to public record, institution, and sanction.

Why it matters

Understanding triadic grammar explains why symbolic systems require external scaffolding (writing, law, institution) to persist. It also explains why artificial systems that mimic surface-level symbolic behavior can do so without the interpretive closure that makes meaning matter.
