Grasping grammar: The haptic turn in language documentation

Language documentation has developed robust standards for recording the optical and acoustic dimensions of speech events, but it less often preserves the material conditions under which force-sensitive grammatical contrasts become interactionally available. In domains involving manipulation, fit, resistance, fracture, and effort, visually similar events may differ in ways that are grammatically relevant yet not recoverable from image or waveform alone. This chapter proposes the Haptic Minimal Pair (HMP) as a controlled elicitation method that holds visual geometry constant while varying a single material parameter such as friction, compliance, mass distribution, or toleranced fit. The proposal is methodological rather than conclusive: drawing on exploratory field observations from Sakha, Telengit, and Cilician Arabic, the chapter presents proof-of-concept cases showing how materially calibrated stimuli can make posture predicates, handling verbs, fracture constructions, and ideophones more observable, more comparable across sessions, and more archivally accountable. It also outlines a compact metadata protocol for preserving both digital design specifications and the physical instantiation of stimuli under CARE-aligned, community-governed archival conditions. The chapter argues that documentary adequacy in force-sensitive domains requires not only recording what speakers say and what cameras capture, but also documenting the calibrated material constraints that make particular grammatical choices pragmatically available.
