Only in Marathi 41
What this means for learners
Marathi and Garo share 14 sounds — roughly 25% of Garo's inventory overlaps with Marathi. Shared sounds are ones a speaker already knows from their native language and will generally produce and perceive accurately without explicit training.
The 12 sounds found only in Garo represent the greatest pronunciation challenge for Marathi 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, Marathi has 41 sounds not used in Garo. Native Garo speakers learning Marathi will face the mirror-image challenge with these sounds.
