The Tajik language has been written in three alphabets over the course of its history: an adaptation of the Perso-Arabic script, an adaptation of the Latin script and an adaptation of the Cyrillic script. Any script used specifically for Tajik may be referred to as the Tajik alphabet, which is written as алифбои тоҷикӣ in Cyrillic characters, الفبای تاجیکی with Perso-Arabic script and alifboji toçikī in Latin script.
The use of a specific alphabet generally corresponds with stages in history, with Arabic being used first, followed by Latin for a short period and then Cyrillic, which remains the most widely used alphabet in Tajikistan. The Bukhori dialect spoken by Bukharan Jews traditionally used the Hebrew alphabet but more often today is written using the Cyrillic variant.
