Language and meaning (subsymbolic self-enrichment)
Language is τ-categorically the self-enrichment of the subsymbolic layer (VII.T20): the system acquires the capacity to name and transport its own pre-symbolic patterns. Meaning is *not* the bridge from symbols to a separate referent — inside a topos, syntax and semantics collapse (VII.T21), and meaning IS form under internal logic. Language adds temporalization (VII.D51), enabling past/present/future as communicable structure.
τ-Definition
Language is τ-categorically the self-enrichment of the subsymbolic layer (VII.T20): the system acquires the capacity to name and transport its own pre-symbolic patterns. Meaning is *not* the bridge from symbols to a separate referent — inside a topos, syntax and semantics collapse (VII.T21), and meaning IS form under internal logic. Language adds temporalization (VII.D51), enabling past/present/future as communicable structure.
Categorical invariant. L = self-enrichment functor of the subsymbolic layer (VII.D52, VII.T20); meaning = internal-logic-readout of structural form, with syntax-semantics collapse inside the topos (VII.T21).

Phenomenological Correlate
Meaning is instantiated wherever structural form is read by the agent's internal logic. Pre-symbolic meaning (felt sense, gesture, music) is genuine meaning (VII.D52); linguistic meaning is its self-enriched readout. Translation across languages succeeds to the extent topoi share structure; what gets 'lost in translation' is exactly the topos-specific structure that does not factor through the bridge.
Examples:
- Felt sense before words — pre-symbolic meaning at the subsymbolic layer (VII.D52)
- Language acquisition — child re-enrichment of subsymbolic patterns into nameable transports
- Untranslatable concepts (Sprachgefühl, saudade, mono no aware) — topos-local structure not factoring through cross-language bridge
- Speech acts (promise, command, question) — pragmatic update operators VII.D54 acting on shared context
Register codomain: Reg_E for descriptive content; Reg_P for normative/pragmatic content; Reg_C for performative/commitment-bearing speech acts. Language is a *multi-register transport medium*; what register a given utterance reads is part of its meaning.
