Short I orYot/Jot (Й й; italics:Й й orЙ й; italics:Й й) (sometimes calledI Kratkoye,Russian:и краткое, Ukrainian: йот) orI with breve,Russian: и с бреве) is a letter of theCyrillic script.[1] It is made of the Cyrillicletter И with abreve.
The short I represents thepalatal approximant/j/, like the pronunciation of⟨y⟩ inyesterday.
Active use of⟨Й⟩ (or, rather, the breve over⟨И⟩) began around the 15th and 16th centuries. Since the middle of the 17th century, the differentiation between⟨И⟩ and⟨Й⟩ is obligatory in the Russian variant of Church Slavonic orthography (used for the Russian language as well). During thealphabet reforms of Peter I, all diacritic marks were removed from the Russian writing system, but shortly after his death, in 1735, the distinction between⟨И⟩ and⟨Й⟩ was restored.[2]⟨Й⟩ was not officially considered a separate letter of the alphabet until the 1930s.
Because⟨Й⟩ was considered to be a vowel and not a consonant, it was not required to take ahard sign when it came at the end of a word in pre-reform orthography.
InRussian, it appears predominantly in diphthongs like/ij/ in широкий (shirokiy 'wide'),/aj/ in край (kray 'end', 'krai'),/ej/ in долей (doley 'portion'),/oj/ in горой (goroy 'mountain'), and/uj/ in буйство (buystvo 'rage').[3] It is used in other positions only in foreign words, such as Йopк (York,not with⟨Ё⟩), including fellow Slavic words like Йовович (Yovovich).
InKazakh, the letter is used to represent a shortɪ sound (e.g. берейік (tr. (Let us)give)). The letter, much like the other 11Cyrillic letters, does not have another Latin version and merges withИи (İi).
InSerbo-Croatian andMacedonian, theCyrillic 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 theLatin letter J (not theletter Y, as in English), for that purpose.
Note that breve in Й may be quite different from ordinary breve, the former having a thinner central part and thicker ends (the opposite holds for ordinary breve). This is often seen in serif fonts, cf.Й (Cyrillic Short I) andŬ (Latin U with breve).
