Turkish Sign Language (Turkish: Türk İşaret Dili, TİD) is the language used by the deaf community in Turkey. As with other sign languages, TİD has a unique grammar that is different from the oral languages used in the region.
TİD uses a two-handed manual alphabet which is very different from the two-handed alphabets used in the BANZSL sign languages. It also uses the tongue in certain phrases.
