Abstract
We present novel evidence for iconicity in core morphophonological grammar by documenting, describing, and analysing two patterns of tonal alternation in Tal (West Chadic, Nigeria). When a non-proximal deixis modifies a noun in Tal, every tone of the modified noun is lowered. When the nominal modifier is a proximal deixis, the final tone of the modified noun is raised. The tone lowering and raising are considered the effects of non-proximal and proximal linkers, which have the tone features [–Upper, –Raised] and [+Raised] as their respective exponents. The realisation and maximal extension of the non-proximal tone features are considered effects of morpheme-specific featural correspondence constraints. Similarly, the exponent of the proximal linker docking on the final TBU is due to the relative ranking of the proximal-specific correspondence constraints. The association of the tone features [–Upper, –Raised] and [+Raised] with non-proximal and proximal linkers, respectively, is in line with crosslinguistic patterns of magnitude iconicity. Given that the local and long-distance realisations of the proximal and non-proximal featural affixes respectively are perceptually similar to deictic gestures, the locality of the featural affixation is considered a novel pattern of iconicity. To motivate this pattern of iconicity, we extend the notion of perceptual motivation in linguistic theory to include the crossmodal depiction of sensory imagery. Consequently, Tal presents evidence for iconicity as a motivation for morphophonological grammar.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
