İske imlâ alphabet

İske imlâ (İske imlâ: ايسكی املا‎, Tatar: Иске имлә İske imlä, pronounced [isˈkɘ̆ imˈlæ], "Old Orthography") is a variant of the Arabic script, used for the Tatar language before 1920, as well as for the Old Tatar language. This alphabet can be referred to as "old" only to contrast it with Yaña imlâ.

Additional characters that could not be found in Arabic and Persian were borrowed from the Chagatai language. The final alphabet was reformed by Qayum Nasiri in the 1870s. In 1920, it was replaced by the Yaña imlâ (which was not an Abjad, but derived from the same source).

This alphabet is currently used by Chinese Tatars, who speak an archaic variant of the Tatar language.
