Tunisian Sign Language
Tunisian Sign Language (Arabic: لغة الإشارة التونسية, romanized: Lughat al-Ishārah al-Tūnisīyah; French: Langue des signes tunisienne) is the sign language used by deaf people in Tunisia. It derives from Italian Sign Language, mixed with indigenous sign.
It is not clear how the language of the Burj as-Salh deaf village relates to indigenous sign and TSL.
