Definition

A communicative kind is what two realizations share when they count as the same act: a repeatable organization of relations among speakers, audiences, norms, commitments and expected responses. Numerically distinct events realize it. A218 §1: “We distinguish numerical identity of concrete events from structural identity of repeatable communicative kinds. A translated performance is not literally the same event as its source, although both may realize corresponding relational organizations.” A218 §2 names the cases where it is clearest: “promising, reprimanding, authorizing, teasing, and establishing conversational commitments”.

Three things are kept apart.

  • Kind. A194 §6: “Structural kind: What invariant pattern does this realization instantiate?”
  • Position. “Structural position: Which relational role does this particular object occupy within the larger configuration?” Promisor and promisee are positions in one kind.
  • Token. The historical event. A191 §2: “A particular promise made at a particular time has a concrete history, speaker, audience, and occurrence.”

The split first appears at A191 §2, as type against token: “Our transport theory often concerns preservation of act type across realizations, rather than numerical identity of a single historical event.” A194 §3 displays it as token identity ≠ structural type identity ≠ representational coordinates, and §6 adds position: “This prevents the theory from using a single invariant signature to solve two different individuation problems.”

What it is not

  • Not the observations of it. A communicative object as an empirical system of constraints (TERM-042) is a pattern of observations, and a kind is what those observations are of.
  • Not the observational class of the family used to observe it (TERM-014). A218 Ch7’s core claim: “A structural kind may be real while remaining indistinguishable under an insufficient family of empirical probes.” An equivalence class relative to a family cannot be unseparated by that same family. It can be by a coarser one, so a kind may coincide with the observational class of a sufficient family; CLAIM-217 proposes competent participants’ uptake as that family.
  • Not a position. A kind has positions; it is not one.
  • Not a token. A translation and its source are two events of one kind, not one event.

The term has a gap. A218 never defines a kind formally. The nearest is §3.1: “Represent candidate relational kinds through structured systems with designated participants, relations, compositions, and transformations.” What makes two such systems the same kind is the open part.

Note of 2026-10-12: the interlocutor’s reading, as advice

The interlocutor’s reading of 2026-10-12 decomposes the communicative process into production, social constitution, interpretation and operational recovery, and says the record’s vocabulary of identity “appears at every level, but with different referents”. This term separates kind, position and token, and has no slot for intended meaning at production. CLAIM-255 files the reading’s split. Recorded as advice; the term is unchanged.
