Place typology and evolution of implosives in Indo-Aryan languages
Bibliographic record
Abstract
Abstract It is widely known that implosives are prevalent in African languages. While Sindhi is considered a textbook example of implosives in Indo-Aryan, the exact distribution of implosives, their development, and place typology are still poorly understood. The present study investigates the typology and evolution of implosives in Indo-Aryan languages and shows that the relationship between implosion and place of articulation in these languages is different from what is seen in global studies. We argue that the relatively high frequency of retroflex implosives in Indo-Aryan languages is due to the high frequency of retroflexes in those languages in general. The findings also indicate that South Asia is another hotspot where languages possess typologically-overloaded inventories of implosives at bilabial, dental-alveolar, retroflex, palatal, and/or velar places of articulation. The aerodynamic constraints and articulatory similarities between implosives and voiced geminates indicate a plausible sound change which led to the evolution of implosives in Indo-Aryan languages.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
