Local Linguistic Convention Formation: A Preliminary Study of Shared-Use Availability

A newly introduced expression can be understood on one occasion without becoming available for subsequent shared use. This paper investigates how local linguistic uses form among already competent participants, with attention to recurrent uptake, correction, contextual extension and continuing support. It reconstructs established convention, grounding and normative-pragmatic accounts before developing a Generative Relational interpretation of historical practice organization. Formation changes the relations through which later applications become intelligible and consequential; its occurrence, evidential identification and justification remain distinct. Typed historical extensions and contextual operations represent introduction, reuse and repair without requiring a fixed complete repertoire. An explicitly restricted nonlinear field model then examines coupled production and uptake after introductory forcing ends. Comparing saturation architectures identifies conditional coexistence and loss of contextual support; a field-transport result separates retained coordinates from retained dynamics. A history-operator algebra makes operation domains and order-sensitive repair inspectable. Published reference-game and conceptual-pact studies constrain the account, while developed workshop and remote editorial examples connect its philosophical, formal and evidential questions. The paper proposes no general measure of meaning, universal convention-formation law or automatic inference from stabilization to legitimate authority. Its contribution is a bounded investigation of shared-use availability and the different obligations involved in explaining its formation.
