"New orthography") was a modified variant of Arabic script that was in use for the Tatar language between 1920 and 1927.
Arguably, Yaña imlâ had as its goal the accommodation of the alphabet to the actual Tatar pronunciation.
Separated Arabic was even incorporated in the early flag of Tatar ASSR, though it was not in real use.
[1][2] Similar to other Turkic languages, Tatar has vowel harmony rules.
There are exceptions in Tatar orthography, meaning words that will have back vowels, but won't have low alef written for them.
For example, the word йорт (yort), meaning "house", is written with low alef, as ࢭیۇرت .
In contrast, the letters Гъ гъ / Ғ ғ (Ğ ğ) (ع) and Къ къ / Ҡ ҡ (Q q) (ق) can only be accompanied by back vowels.
