The soft sign (Ь, ь, italics Ь, ь) also known as the front yer, front jer, or er malak (lit. "small er") is a letter of the Cyrillic script. In Old Church Slavonic, it represented a short (or "reduced") front vowel. As with its companion, the back yer ъ, the vowel phoneme that it designated was later partly dropped and partly merged with other vowels.


In the modern Slavic Cyrillic writing systems in which it appears (all East Slavic languages and Bulgarian and Church Slavic), it does not represent an individual sound but indicates palatalization of the preceding consonant.

Uses and meanings

Palatalization sign

The soft sign is normally written after a consonant and indicates its softening (palatalization) (for example Ukrainian батько 'father'). Less commonly, the soft sign just has a grammatically determined usage with no phonetic meaning (like Russian : туш 'fanfare' and тушь 'India ink', both pronounced /tuʂ/ but different in grammatical gender and declension). In East Slavic languages and some other Slavic languages (such as Bulgarian), there are some consonants that do not have phonetically different palatalized forms but corresponding letters still admit the affixing soft sign.

The Serbian Cyrillic alphabet has had no soft sign as a distinct letter since the mid-19th century: palatalization is represented by special consonant letters instead of the sign (some of these letters, such as Њ or Љ , were designed as ligatures with the grapheme of the soft sign). The modern Macedonian alphabet, based on the Serbian Cyrillic variant, has had no soft sign since its creation, in 1944.

Before a vowel in East Slavic languages

Between a consonant and a vowel, the soft sign bears also a function of "iotation sign": in Russian, vowels after the soft sign are iotated (compare Russian льют /lʲjut/ '(they) pour/cast' and лют /lʲut/ '(he is) fierce'). The feature, quite consistent with Russian orthography, promulgated a confusion between palatalization and iotation, especially because ь usually precedes so-called soft vowels. Combinations ья (ya), ье (ye), ьё (yo) and ью (yu) give iotated vowels, like corresponding vowel letters in isolation (and word-initially), and unlike its use immediately after a consonant letter in which palatalization can occur but not iotation. In those cases, ь may be considered as a sign indicating that a vowel after it is pronounced separately from the previous consonant, but that is the case neither for ьи (yi) nor for ьо (yo), because these vowels are not iotated in isolation. The latter case, though, is rarely used in Russian (only in loanwords such as бульон) and can be seen as a replacement of phonetically identical ьё, which gets rid of an "inconvenient" letter ё . In Ukrainian and Bulgarian, the spelling ьо indicates palatalization, not iotation.

ъ, an "unpalatalization sign", also denotes iotation, as in the case of ъя, ъе, ъё and ъю in Russian.

Similarly, the soft sign may denote iotation in Belarusian and Ukrainian, but it is not used so extensively as in Russian. Ukrainian uses a quite different repertoire of vowel letters from those of Russian and Belarusian, and iotation is usually expressed by an apostrophe in Ukrainian. Still the soft sign is used in Ukrainian if the sound preceded by an iotated vowel is palatalized.

In Bulgarian

Among Slavic languages using the Cyrillic script, the soft sign has the most limited use in Bulgarian: since 1945, the only possible position is one between consonants and о (such as in names Жельо, Кръстьо, and Гьончо).

As a vowel in Slavic studies

In Slavistic transcription, Ь and Ъ are used to denote Proto-Slavic extra-short sounds /ĭ/ and /ŭ/ respectively (slověnьskъ adj. 'Slavonic'), like Old Slavonic orthography.



The soft sign does not occur after vowels in Slavic languages, but the а ь digraph for / æ / or / a / was introduced to some non-Slavic Cyrillic-based alphabets such as Chechen, Ingush and various Dagestanian languages such as Tabasaran. Similarly, the о ь digraph was introduced for / œ / or / ø /, and у ь for / y /, plus iotated forms such as ю ь and я ь as required. This use of ь is similar to a trailing e as used in, for example, German, when umlauts are unavailable (cf. Goethe).

There were proposals to use the same for Turkic languages, [1] as a replacement to Cyrillic Schwa (Ә) for ə or /æ/. Unlike Schwa, which is not represented in many Cyrillic character repertoires such as Windows-1251, both а and ь are readily available as letters of the basic modern Russian alphabet.


Like the hard sign and the palochka, many languages use the soft sign forms digraphs to represent sounds which are phonetically similar, yet distinct phonemes from the bare letter. For example, while г represents / g /, гь represents / ɣ / in Crimean Tatar, / ɦ / in Archi, and / h / in Avar and Tabasaran.


Under normal orthographic rules, it has no uppercase form, as no word begins with the letter. However, Cyrillic type fonts normally provide an uppercase form for setting type in all caps or for using it as an element of various serial numbers (like series of Soviet banknotes) and indices (for example, there was once a model of old Russian steam locomotives marked "Ь"  ru:Паровоз Ь).

In the romanization of Cyrillic, the soft sign is typically transliterated with U+02B9ʹ MODIFIER LETTER PRIME . Sometimes U+02BCʼ MODIFIER LETTER APOSTROPHE is used, or the soft sign may be ignored if it is in a position that it does not denote iotation, for example: Тверь=Tver, Обь=Ob. It can also be transcribed "y" or "i" if preceding a vowel.

In Belarusian it is romanized as a combining acute, e.g., зь ź, ць ć, нь ń, ль ĺ.

<span class="mw-page-title-main">Yery</span> Cyrillic letter ⟨ы⟩

Yeru or Eru, usually called Y[ɨ] in modern Russian or Yery or Ery historically and in modern Church Slavonic, is a letter in the Cyrillic script. It represents the close central unrounded vowel after non-palatalised (hard) consonants in the Belarusian and Russian alphabets, and after any consonant in most of Rusyn standards, where it represents the unrounded close-mid back unrounded vowel sound.

Russian is an East Slavic language of the Indo-European family. All Indo-European languages are descendants of a single prehistoric language, reconstructed as Proto-Indo-European, spoken sometime in the Neolithic era. Although no written records remain, much of the culture and religion of the Proto-Indo-European people can also be reconstructed based on their daughter cultures traditionally and continuing to inhabit most of Europe and South Asia, areas to where the Proto-Indo-Europeans migrated from their original homeland.

<span class="mw-page-title-main">Ukrainian alphabet</span> Alphabet that uses letters from the Cyrillic script

The Ukrainian alphabet is the set of letters used to write Ukrainian, which is the official language of Ukraine. It is one of several national variations of the Cyrillic script. It comes from the Cyrillic script, which was devised in the 9th century for the first Slavic literary language, called Old Slavonic. Since the 10th century, it became used in the Kyivan Rus' for Old East Slavic, from which the Belarusian, Russian, Rusyn, and Ukrainian alphabets later evolved. The modern Ukrainian alphabet has 33 letters in total: 20 consonants, 2 semivowels, 10 vowels and 1 palatalization sign. Sometimes the apostrophe (') is also included, which has a phonetic meaning and is a mandatory sign in writing, but is not considered as a letter and is not included in the alphabet.

<span class="mw-page-title-main">Ukrainian Ye</span> Сharacter of the Cyrillic script

Ukrainian Ye is a character of the Cyrillic script. It is a separate letter in the Ukrainian alphabet, the Pannonian Rusyn alphabet, and both the Carpathian Rusyn alphabets; in all of these, it comes directly after Е. In modern Church Slavonic, it is considered a variant form of Ye (Е е). Until the mid-19th century, Є/є was also used in Romanian and Serbian. Other modern Slavonic languages may use Є/є shapes instead of Е/е for decorative purposes. Then, the letter is usually referred to by the older name Yest. If the two need to be distinguished, the descriptive name Broad E is sometimes used.

In Slavic languages, iotation is a form of palatalization that occurs when a consonant comes into contact with a palatal approximant from the succeeding phoneme. The is represented by iota (ι) in the Cyrillic alphabet and the Greek alphabet on which it is based. For example, ni in English onion has the sound of iotated n. Iotation is a phenomenon distinct from Slavic first palatalization in which only the front vowels are involved, but the final result is similar.

The history of the Slavic languages stretches over 3000 years, from the point at which the ancestral Proto-Balto-Slavic language broke up into the modern-day Slavic languages which are today natively spoken in Eastern, Central and Southeastern Europe as well as parts of North Asia and Central Asia.

The letter is called back yer or back jer and yor or jor in the pre-reform Russian orthography, in Old East Slavic, and in Old Church Slavonic.

<span class="mw-page-title-main">Cyrillic alphabets</span> Related alphabets based on Cyrillic scripts

Numerous Cyrillic alphabets are based on the Cyrillic script. The early Cyrillic alphabet was developed in the 9th century AD and replaced the earlier Glagolitic script developed by the Byzantine theologians Cyril and Methodius. It is the basis of alphabets used in various languages, past and present, Slavic origin, and non-Slavic languages influenced by Russian. As of 2011, around 252 million people in Eurasia use it as the official alphabet for their national languages. About half of them are in Russia. Cyrillic is one of the most-used writing systems in the world.

The Cyrillic script family contains many specially treated two-letter combinations, or digraphs, but few of these are used in Slavic languages. In a few alphabets, trigraphs and even the occasional tetragraph or pentagraph are used.

The following list is a comparison of basic Proto-Slavic vocabulary and the corresponding reflexes in the modern languages, for assistance in understanding the discussion in Proto-Slavic and History of the Slavic languages. The word list is based on the Swadesh word list, developed by the linguist Morris Swadesh, a tool to study the evolution of languages via comparison, containing a set of 207 basic words which can be found in every language and are rarely borrowed. However, the words given as the modern versions are not necessarily the normal words with the given meaning in the various modern languages, but the words directly descended from the corresponding Proto-Slavic word. The list here is given both in the orthography of each language, with accent marks added as necessary to aid in pronunciation and Proto-Slavic reconstruction. See below for a capsule summary of how to pronounce each language, as well as some discussion of the conventions used.

<span class="mw-page-title-main">Proto-Slavic language</span> Proto-language of all the Slavic languages

Proto-Slavic is the unattested, reconstructed proto-language of all Slavic languages. It represents Slavic speech approximately from the 2nd millennium B.C. through the 6th century A.D. As with most other proto-languages, no attested writings have been found; scholars have reconstructed the language by applying the comparative method to all the attested Slavic languages and by taking into account other Indo-European languages.
