Only in Tigrinya 51
What this means for learners
Tigrinya and Dafla share 15 sounds — roughly 23% of Dafla's inventory overlaps with Tigrinya. 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 Dafla represent the greatest pronunciation challenge for Tigrinya 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, Tigrinya has 51 sounds not used in Dafla. Native Dafla speakers learning Tigrinya will face the mirror-image challenge with these sounds.
