Ya with diaeresis (Я̈ я̈; italics:
Я̈ я̈) is a letter of the Cyrillic script.Ya with diaeresis is used in the Selkup language.
In Russian, ya with diaeresis saw rare use prior to the 1918 orthography reform to indicate that a stressed letter ya (Russian: Я) should be pronounced as pronounced as //jo// instead of the expected pronounced as //ja//, in a similar fashion to the role of yo (Russian: Ё).[1] For example, the modern pronouns Russian: [[wikt:её|её]] and Russian: [[wikt:неё|неё]] were formerly spelled Russian: [[wikt:ея̈|ея̈]] and Russian: [[wikt:нея̈|нея̈]] in the genitive and possessive, due to their historical pronunciations as pronounced as //jɪˈja// and pronounced as //nʲɪˈja//, which had since shifted to pronounced as //jɪˈjo// and pronounced as //nʲɪˈjo//. As with the letter yo, use of the diaeresis was rare outside of learning materials and dictionaries, and following the reform the letter was replaced with yo outright.
