What this means for learners
NYIMANG and Kabardian share 9 sounds — roughly 14% of Kabardian's inventory overlaps with NYIMANG. Shared sounds are ones a speaker already knows from their native language and will generally produce and perceive accurately without explicit training.
The 54 sounds found only in Kabardian represent the greatest pronunciation challenge for NYIMANG 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, NYIMANG has 16 sounds not used in Kabardian. Native Kabardian speakers learning NYIMANG will face the mirror-image challenge with these sounds.
