Yo, Jo or Io (Ё ё; italics:
Ё ё; pronounced as /ru/) is a letter of the Cyrillic script. In Unicode, the letter is named CYRILLIC CAPITAL/SMALL LETTER IO.In English, the letter Yo is romanized using the Latin ë (according to the ALA–LC and British Standards), ë (yë word-initially) (BGN/PCGN) or yo/jo (orthographic transcription) for Russian, and as i͡o (ALA–LC), yo (BGN/PCGN), or ë (BSI) for Belarusian. In international systems, Yo is romanized as ë (ISO 9).
It was derived from the Cyrillic letter Ye (Е е).
This section describes the pronunciation in Russian and Belarusian. Other languages may have subtle differences.
The letter is a stressed syllable in the overwhelming majority of Russian and Belarusian words. In Russian, unstressed occurs only in compound numerals and a few derived terms, wherein it is considered an exception.
It is a so-called iotated vowel. In initial or post-vocalic position, it represents the sounds pronounced as //jo//, like in 'York'. The same applies if is preceded by either or .
The letter also indicates the phoneme pronounced as //o// together with palatalization of the preceding consonant (if it is possible). No pronounced as //j// sound occurs between the consonant and the vowel in this case.
Exact pronunciation of the vowel sound of can vary because of allophony in Slavic languages. In Russian, it is pronounced pronounced as /[jɵ]/, with an pronounced as /link/ vowel similar to bird in New Zealand or South African English; see palatalization for some background.
Yo was first used in Russian, but its status in that language is now ambiguous. Yo occurs as a discrete letter in the Cyrillic alphabets of Belarusian, Rusyn, Mongolian and many Caucasian and Turkic languages.
The letter Yo or Jo is the seventh letter of the alphabet, but although it indicates a distinct sound from Ye, it is often treated as the same letter for alphabetisation and sorting. In the dictionary, Russian: ёж (hedgehog) comes after Russian: едо́к (eater) and before Russian: е́здить (to go).
represents the phoneme pronounced as //o// after pronounced as //j// or a soft consonant (or occasionally after,), and it should always be stressed. It alternates with, written in non-stressed positions. Unstressed appears only in rare loanwords, in compound words (in this case it may be considered to have secondary stress; most notably, occurs in words containing the prefixes Russian: трёх- 'three-' and Russian: четырёх- 'four-'), in derivatives of the name of the letter itself (Russian: ёфика́тор - yoficator), in loanwords (Russian: кёнигсбе́ргский - adjective from German: [[Königsberg]], Russian: сёрфинги́ст from English: surfing - surfer, Russian: сёдзё - Japanese: [[shōjo]], Russian: гёмбёц - Hungarian: [[gömböc]]).
In modern Russian, the reflex of Common Slavonic pronounced as //e// under stress and following a palatalized consonant but not preceding a palatalized consonant is pronounced as //o//. For examples, compare Russian: л'''ё'''т ("flight") from *letъ[1] in contrast to Russian: л'''е'''щ ("bream") from *leščь;[1] or Russian: ос'''ё'''тр pronounced as /[ɐˈsʲ'''ɵ'''tr]/ ("sturgeon") from *esetr[2] in contrast to Russian: ос'''e'''ть pronounced as /[ɐˈsʲ'''e'''tʲ]/ ("granary, rack for drying grain") from *esetь.[2] However, since the sound change took place after the introduction of writing, the letter continued to be written in that position. It was not until the 18th century that efforts were made to represent the sound in writing.
From the mid-1730s, it appears sporadically as or . This digraph and new letter for the sound pronounced as //ɡ// were proposed to be added to the official alphabet in 1783 at a session of the Russian Academy under the presidency of Princess Yekaterina Romanovna Vorontsova-Dashkova, but both propositions were rejected by the academicians and the Metropolitan of Novgorod and Saint Petersburg Gavriil. At that time, the sounds pronounced as //jo//—pronounced as //ʲo// and pronounced as //ɡ// were common in everyday Central Russian speech, but Church-Slavonic-styled pronunciation with pronounced as //je//–pronounced as //ʲe// and pronounced as //ɣ// was preferred when reading literary texts.
The sounds [jo] (and [o] after soft consonants) that developed in Russian pronunciation, for a long time were not distinguished from [je] (and [e] after soft consonants) in writing. In the mid-18th century, a ligature in the form of the letters IO with a top joiner was introduced, but it was cumbersome and used rarely. Other variants in use were: о, ьо, їô, ió, ио.
In 1797, instead of existing options, the letter "Ё" was created by Russian Imperial historian, writer, poet and critic Nikolay Mikhailovich Karamzin. It was used for the first time in the 2nd book of "Aonides" in his poem "Sophistiated Solomon's Wisdom, or Thoughts Selected from Ecclesiastes" to create a rhyme between the words слёзы [ˈslʲɵzɨ] and розы [ˈrozɨ]. In other places of the poem he used the spelling слезы [ˈslʲezɨ].[3] [4] [5] [6]
The diaeresis ◌̈ does not appear above any other letter in Russian. It serves no purpose except to differentiate between and .
Except for a brief period after World War II, the use of was never obligatory in standard Russian orthography. By and large, it is used only in dictionaries and in pedagogical literature intended for children and students of Russian as a second language. Otherwise, is used, and occurs only when it is necessary to avoid ambiguity (such as to distinguish between Russian: все ("everybody") and Russian: всё ("everything") when it is not obvious from the context) or in words (principally proper nouns) whose pronunciation may not be familiar to the reader. Recent recommendations (2006) from the Russian Language Institute are to use in proper nouns to avoid an incorrect pronunciation.[7] It is permitted, however, to mark whenever it occurs,[7] which is the preference of some Russian authors and periodicals.
The fact that is frequently replaced with in print often causes some confusion to both Russians and non-Russians, as it makes it more difficult for Russian words and names to be transcribed. One recurring problem is with Russian surnames, as both Russian: -ев (-ev/-yev) and Russian: -ёв (-yov/-ov) are common endings. Thus, the English-speaking world knows two leaders of the former Soviet Union as Khrushchev and Gorbachev, but their surnames end in Russian with Russian: -ёв, better transcribed -yov/-ov (which is why many English-speakers pronounce these names as if they end in -ov but they spell them with -ev).
The advent of the computer has had a great influence on the process of substitution with for a counterintuitive reason: currently, the Russian alphabet contains 33 letters including, and codepage designers usually prefer to omit so that all Russian letters can be placed into sections of 16 letters (16, like other powers of 2, is often preferred in computing over other numbers). Some examples are pre-Unicode character pages 866 for Microsoft DOS and 1251 for Microsoft Windows. Since in both cases, was placed outside its alphabetically correct position, it made text sorting more complex. Software developers would then choose to substitute all letters with at an early stage of text processing to simplify later stages.
can be used in Russian transcription of foreign words originating from languages that use the sound pronounced as //ø// or pronounced as //œ//, spelled eu/ö/ő/ø (French, Germanic languages other than English, Uralic languages), such as "Gerhard Schröder", whose last name is transliterated as Russian: Шрёдер because of its similarity to the native Russian sound [ɵ]. This letter is also often used for transcribing the English vowel pronounced as //ɜr//, in names like Russian: Роберт Бёрнс for "Robert Burns" or Russian: Хёрст for "Hearst"/"Hurst"/"Hirst". However, several authoritative sources recommend the transcription ер for pronounced as //ɜr//. Word-initial and post-vocalic pronounced as //ø// or pronounced as //œ// is usually transcribed in Russian (but in names from Turkic languages).
However, the sound pronounced as /[jo]/, in words from European languages, is normally transcribed into Russian as in initial and post-vocalic position and after consonants: Russian: Нью-Йорк for "New York" and Russian: батальон for "battalion". An apparent exception is the Russian word for "serious", which is spelled Russian: серьёзный rather than Russian: сериозный. However, this is due to the fact that this word stems from French sérieux with an pronounced as //ø// sound. (In the 19th and the early 20th century, both spellings were in use.[8] The spelling with — in the pre-1918 orthography— was based on Latin seriosus.)
The letter is normally used to transcribe the Japanese into Russian Cyrillic, appearing in the Russian transcription of Japanese that would appear as yo (よ), kyo (きょ), sho (しょ) etc. in Hepburn Romanization, but there are a few traditional spellings which break this rule. For example, "Yokohama" is spelled in Russian with, not . Similarly, is used to transcribe into Russian Cyrillic the Korean sounds romanized as, and confusingly also for with the same letter. In such transcriptions, as well as in languages other than Russian where ё is used, the use of ё rather than е is obligatory.
The -less Bulgarian uses pronounced as //ʲo// (after consonants) and pronounced as //jo// (word-initial and after vowels) for transcribing the foreign vowels pronounced as //ø// or pronounced as //œ//, and also for French labialized schwa: "de" and "le" are transcribed Russian: де and Russian: ле in Russian but Russian: дьо and Russian: льо in Bulgarian.
However, in Ukrainian (which also lacks the letter and uses for pronounced as //jo// and for pronounced as //ʲo//), the standard way for transcribing pronounced as //ø// or pronounced as //œ// in foreign names is pronounced as //e//.
It is thought that the letter is found in at least 2500 surnames used in Russia and other states of the former USSR. It is common for a person who has one of these surnames to possess some legal documents (passports, identification cards, marriage and birth certificates, property ownership papers, etc.) where the name is written with a, and some that use the simple instead. In other situations, a child's birth certificate may have a and the parents' identity papers all have . On occasion such mismatches caused problems to citizens who receive inheritance or complete property transactions.[9]
Yo is the seventh letter of the Belarusian alphabet and the ninth letter of the Prešov Rusyn alphabet of Slovakia. In the Pannonian Rusyn alphabet, yo is absent.
In Belarusian and Prešov Rusyn, the letters and are separate and not interchangeable.
Unlike the Russian spelling system, is mandatory in the Cyrillic alphabet used by Dungan. In that Sinitic language, the / distinction is crucial, as the former is used such as to write the syllable that would have the pinyin spelling of ye in Standard Chinese, and the latter is used for the syllable that appears as yao in pinyin. is very prominent in Dungan spelling since the very common syllable appearing as yang in Pinyin is spelled in Dungan.
In the Cyrillic alphabet for the Mongolian language, is the seventh letter, and it is always different from . It represents the syllable /jɔ/. For example, the word for "two" in Mongolian, "khoyor", is spelled as хоёр.
In the Tajik language, ⟨ё⟩ is used for the syllable /jɔː/.
In some older alphabets used for Ukrainian, such as Panteleimon Kulish's Kulishivka's alphabet, was formerly used for the sound pronounced as //jo//—pronounced as //ʲo//. This letter no longer exists in the modern Ukrainian alphabet.
In modern Ukrainian spelling, the sound pronounced as //jo//—pronounced as //ʲo// is written as after soft consonants in the middle of words (such as "нього", "him" after a preposition), and elsewhere (such as "його", "him"). The standard way to transcribe the foreign phonemes pronounced as //ø// or pronounced as //œ// in Ukrainian is with the letter .
There are computer software or extension that is used to restore the Cyrillic letter Yo ⟨Russian: Ё⟩ in Russian texts in places where the letter Ye ⟨Russian: Е⟩ was used instead. ORFO and Yoficator are examples of such.
