Only in Kurukh 39
What this means for learners
Kurukh and Sanskrit share 29 sounds — roughly 43% of Sanskrit's inventory overlaps with Kurukh. Shared sounds are ones a speaker already knows from their native language and will generally produce and perceive accurately without explicit training.
The 16 sounds found only in Sanskrit represent the greatest pronunciation challenge for Kurukh speakers. The adult brain tends to map unfamiliar sounds onto the closest native equivalent — a process that produces the characteristic "accent" of a second-language speaker. Learning to hear and produce these sounds as distinct requires focused ear training, not just repetition.
Conversely, Kurukh has 39 sounds not used in Sanskrit. Native Sanskrit speakers learning Kurukh will face the mirror-image challenge with these sounds.
