Short I (Cyrillic)

Active use of (or, rather, the breve over ) began around the 15th and 16th centuries. Since the middle of the 17th century, the differentiation between and is obligatory in the Russian variant of Church Slavonic orthography (used for the Russian language as well). During the alphabet reforms of Peter I, all diacritic marks were removed from the Russian writing system, but shortly after his death, in 1735, the distinction between and was restored. was not officially considered a separate letter of the alphabet until the 1930s. Because is always soft, it was not required to take a hard sign when it came at the end of a word in pre-reform orthography. ==Usage==

In Russian, it appears predominantly in diphthongs like in широкий (shirokiy 'wide'), in край (kray 'end', 'krai'), in долей (doley 'portion'), in горой (goroy 'mountain'), and in буйство (buystvo 'rage'). It is used in other positions only in foreign words, such as Йopк (York, not with), including fellow Slavic words like Йовович (Yovovich). In Kazakh, the letter is used to represent a short ɪ sound (e.g. берейік (tr. (Let us) give)). The letter, much like the other 11 Cyrillic letters, does not have another Latin version and merges with Ии (İi). In Serbo-Croatian and Macedonian, the Cyrillic letter Јe is used to represent the same sound. Latin-based Slavonic writing systems, such as Polish, Czech and the Latin version of Serbo-Croatian use the Latin letter J (not the letter Y, as in English), for that purpose. ==Related letters and other similar characters==
