Shor (endonym: шор тили, şor tili; тадар тили, tadar tili), or Kuznets Tatar, is a critically endangered Turkic language spoken by about 2,800 people in a region called Mountain Shoriya, in Kemerovo Oblast in Southwest Siberia, although the entire Shor population in this area is over 12,000 people.

In spite of all the efforts by the missionaries, the percentage of literacy among the native population increased very slowly — by the beginning of the 20th century they constituted only about 1% of the Shors.

This however considerably complicated the process of learning; thus in 1938, the same author together with Georgij Babuskin created a new variant of the primer based on the Cyrillic alphabet, of which several editions have been published since then.

A Latin alphabet for the Shor language was introduced in 1930: A a, B в, C c, D d, Ə ə, F f, G g, Ƣ ƣ, I i, J j, K k, Q q, M m, N n, Ꞑ ꞑ, O o, Ө ө, P p, R r, S s, T t, U u, V v, Ş ş, Z z, Ƶ ƶ, L l, Ь ь, Y y, Į į.

After reforms in 1980 it reached its present form: А а, Б б, В в, Г г, Ғ ғ, Д д, Е е, Ё ё, Ж ж, З з, И и, Й й, К к, Қ қ, Л л, М м, Н н, Ң ң, О о, Ӧ ӧ, П п, Р р, С с, Т т, У у, Ӱ ӱ, Ф ф, Х х, Ц ц, Ч ч, Ш ш, Щ щ, Ъ ъ, Ы ы, Ь ь, Э э, Ю ю, Я я.
