compositionality-carnap-1947-first-explicit

Summary

This pins down that the idea "the meaning of a whole is built from the meanings of its parts" was first spelled out as a formal principle by Carnap in 1947, not later. It matters because it sets the starting point for the history of compositionality, meaning any subsequent work in semantics, logic, or language modeling that claims to introduce the principle is really building on Carnap's groundwork rather than originating it.
