Languages of Chad

Chad has two official languages, Arabic and French, and over 120 indigenous languages. A vernacular version of Arabic, Chadian Arabic, is a lingua franca and the language of commerce, spoken by 40–60% of the population.^[1] French is widely spoken in the main cities such as N'Djamena and by most men in the south of the country. Most schooling is in French.^[2] The language with the most first-language speakers is probably Ngambay, with around one million speakers.^[3]

Chadian Sign Language is a variant of Nigerian Sign Language, a dialect of American Sign Language; Andrew Foster introduced ASL in the 1960s, and Chadian teachers for the deaf train in Nigeria.
