s and surrounding consonants, from . C is hard (non-palatalized) consonant, Ç is soft (palatalized) consonant. This chart uses frequencies to represent the basic vowel triangle of the Russian language.|left|class=skin-invert-image Russian has five to six vowels in
stressed syllables, and in some analyses , but in most cases these vowels have merged to
only two to four vowels when unstressed: (or ) after hard consonants and after soft ones. A long-standing dispute among linguists is whether Russian has five vowel
phonemes or six; that is, scholars disagree as to whether constitutes an
allophone of or if there is an independent phoneme . The five-vowel analysis, taken up by the Moscow school, rests on the
complementary distribution of and , with the former occurring after hard (non-
palatalized) consonants (e.g. 'to live', 'thorn, spine', 'circus', etc.) and after soft (palatalized) consonants (e.g. 'shield', 'rank', etc.), at the word beginnings, and after vowels. The allophony of the stressed variant of the open is largely the same, yet no scholar considers and to be separate phonemes (which they are in e.g.
Slovak). The five-vowel point of view is further supported by the following facts: • Some endings have after soft consonants and after hard consonants, e. g. (gen. sg. of 'water'), (gen. sg. of 'ground, land, earth'). Proto-Slavic *y could correspond to either *ę̇ or *i after palatals (see
Proto-Slavic language); in Russian, the soft-stem counterpart of the hard-stem ending regularized to . • When a word or morpheme (root or prefix) beginning with is preceded by a hard consonant, becomes : 'name' — 'without name' and 'nameless', 'history' — 'events preceding, events leading up, backstory, prehistory', исла́м 'Islam' — панислами́зм [ˌpanɨsɫʌˈmʲizm], 'Pan-Islamism', изме́на 'treason' — госизме́на 'high treason'. According to the current spelling rules standardized in 1956, the letter is used instead of the morpheme-initial in words with Slavic prefixes (except меж- and сверх-) whereas words with non-Slavic prefixes and compound words conserve the morpheme-initial in the spelling. Pre-1956 spelling varied: whereas for common words such as the spelling with was well established long ago, less common words such as 'previous' were often spelled with in the 19th century; however,
Yakov Grot prescribed spelling them with . For even less common words, spelling practice varied between , , and even in the first half of the 20th century. The six-vowel view, held by the Saint-Petersburg (Leningrad) phonology school, points to several phenomena to make its case: • Native Russian speakers' ability to articulate in isolation: for example, in the names of the letters and . • Rare instances of word-initial , including the minimal pair 'to produce the sound ' and 'to produce the sound ы', as well as borrowed names and toponyms, like , the name of a river and several villages in the
Komi Republic. • Morphological alternations between non-palatalized consonants without any following vowel or before and palatalized consonants before , like ('ready' adjective, masculine, short-form), ('ready' adjective, masculine), and ('to get ready; to prepare' verb, transitive), signifying that palatalizes an inherently non-palatalized
underlying consonant while does not. The different behaviour of the underlying combination "hard consonant+" in prefix-root and root-suffix bounds can be explained historically. In Old East Slavic, words such as (from 'under' + 'to take') had the extra-short vowel before ; the combination changed to , which is reflected in the modern Russian spelling 'to lift' (although contemporary Russian prefers the form with the epenthetic from 'to take off', from Old East Slavic 'off' + 'to take' but reanalysed as + ). The Old East Slavic prefixes ending in (, , etc.) did not have the final , but in Modern Russian after them becomes by analogy, except the verb 'to levy, to take monies'. However, the alternations between hard and soft consonants occur not only when the soft consonant occurs before or , but also sometimes when the soft consonant occurs before or or without any following vowel (which is historically explained by origin of those vowels and vowel absence in Old East Slavic , , and ), which can lead to minimal pairs such as ('ready' adjective, feminine, short-form) — ('getting ready; preparing', adverbial participle), ('ready' adjective, masculine, short-form) — ('get ready; prepare', imperative). No matter whether the five-vowel or six-vowel point of view is used, the phonological explanation of those alternations requires either a separate "palatalization phoneme" or palatalization as a phoneme alternation occurring before particular morphemes (including null morphemes). Hence, the difference between and can be explained using the five-vowel point of view. The most popular view among linguists (and the one taken up in this article) is that of the Moscow school, though Russian pedagogy has typically taught that there are six
vowels (the term
phoneme is not used). Reconstructions of
Proto-Slavic show that and (which correspond to and ) were separate phonemes. On the other hand, after the
first palatalization, Old East Slavic *
i and *
y contrasted only after alveolars and labials: after palatals only *
i occurred, and after velars only *
y occurred. With the development of phonemic palatalized alveolars and labials, *
i and *
y no longer contrasted in any environment and were reinterpreted as allophones of each other, becoming a single phoneme /i/. Even so, this reinterpretation entailed no mergers and no change in the pronunciation. Subsequently, sometime between the twelfth and fourteenth centuries, the allophone of /i/ occurring after a velar consonant changed from [ɨ] to [i] with subsequent palatalization of the velar, turning old Russian into modern and old into modern .
Allophony Russian vowels are subject to considerable
allophony, subject to both stress and the palatalization of neighboring consonants. In most unstressed positions, in fact, only three phonemes are distinguished after hard consonants, and only two after soft consonants. Unstressed and have merged to (a phenomenon known as ); unstressed and have merged to (); and all four unstressed vowels have merged after soft consonants, except in the absolute final position in a word. None of these mergers are represented in writing.
Front vowels When a preceding consonant is
hard, is retracted to . Formant studies in demonstrate that is better characterized as slightly
diphthongized from the
velarization of the preceding consonant, implying that a phonological pattern of using velarization to enhance perceptual distinctiveness between hard and soft consonants is strongest before . When unstressed, becomes
near-close; that is, following a hard consonant and in most other environments. Between soft consonants, stressed is raised, as in ('to drink'). When preceded
and followed by
coronal or
dorsal consonants, is fronted to . After a cluster of a labial and , is retracted, as in ('to float'); it is also slightly diphthongized to . In native words, only follows unpaired (i.e. the
retroflexes and ) and soft consonants. After soft consonants (but not before), it is a mid vowel (hereafter represented without the diacritic, for simplicity), while a following soft consonant raises it to close-mid . Another allophone, an open-mid , occurs word-initially and between hard consonants. Preceding hard consonants retract to and so that ('gesture') and ('target') are pronounced and respectively. In words borrowed from other languages, often follows hard consonants; this foreign pronunciation usually persists in Russian for many years until the word is more fully adopted into Russian. For instance, (from French
chauffeur) was pronounced in the early twentieth century, but is now pronounced . On the other hand, the pronunciations of words such as ('hotel') retain the hard consonants despite a long presence in the language.
Back vowels Source: • [kərɐˈvaj] ('
korovai'), which is from PSl. '''' etc. • Spelling those words with ⟨а⟩ was already common in the 18th century, but it co-existed with the spelling with ⟨о⟩ (), conforming to etymology of those words. Dictionaries often gave both spellings. Finally the spelling of those words with ⟨а⟩ was set by the 1956 orthographic codification (orthographic rules and spelling dictionary), based on the spread of usage.
Vowel mergers In terms of actual pronunciation, there are at least two different levels of vowel reduction: vowels are less reduced when a syllable immediately precedes the stressed one, and more reduced in other positions. This is particularly visible in the realization of unstressed and , where a less-reduced allophone appears alongside a more-reduced allophone . The pronunciation of unstressed is as follows: • (sometimes transcribed as ; the latter is phonetically correct for the standard Moscow pronunciation, whereas the former is phonetically correct for the standard Saint Petersburg pronunciation; this article uses only the symbol ) appears in the following positions: • In the syllable immediately before the stress, when a hard consonant precedes: e.g. ('people, nation'), ('frost'), ('firewood'), and ('grass'). • In absolute word-initial position: e.g. ('vanguard'), ('
kitchen garden'). • In
hiatus, when the vowel occurs twice without a consonant between; this is written , , , or : ('to use common sense, to reason'). • appears elsewhere, when a hard consonant precedes: ('cloud'), ('berry'). • In absolute word-final position, may occur instead, especially at the end of a
syntagma. • When a soft consonant or precedes, both and merge with and are pronounced as . Example: ('tongue'), ('hedgehogs') ( is written as in these positions; compare 'hedgehog'). • This merger also tends to occur after formerly soft consonants now pronounced hard (, , ), where the pronunciation occurs; e.g. 'to stir ~ to move ~ to bulge'. This always occurs when the spelling uses the soft vowel variants, e.g. ('wife') vs. ('wives') (but 'shock (n.)' vs. 'to shock (v.)'; unstressed spellings , are used only in loanwords). However, also occurs in a few word roots where the spelling writes a hard . Examples: • 'regret', whence ('to regret'), к сожале́нию ('unfortunately'). • ~ ('horse [sg. nom. & acc.]'), whence , ('horses' [pl. gen. & acc.]'). • in numbers: e.g. ('twenty [gen., dat., prep.]'), ('thirty [instr.]'). • ~ ('rye [adj. m. nom.]'). • ~ ('jasmine [n. sg. nom. & acc.]'). • After those now-hardened formerly-soft consonants (, , ) and in word-final position, unstressed and unstressed (the latter written as ) merge and are pronounced , as in: • ('pollen') vs. ('murderer, assassin'), • ('most strictly',
adv.) vs. ('good', neut. predic. or 'well', adv.), • ('similar(ly)', neut. predic. or adv.), vs. ('fresh(ly)', neut. predic. or adv.), and • ('sapling, small tree') vs. its synonym . • Yet word-final unstressed after , , and is also pronounced by some speakers: e.g. , "trough, washing tub (diminutive) (nom. sg.)" (as it rhymes with "water (dim.) (gen. sg.)" in the song "the little chickens"). • These processes occur even across word boundaries as in ('under the sea'). The pronunciation of unstressed is after soft consonants and , and word-initially ( ('stage'); ('
roe'); ; ('to surprise'), etc.), but after hard consonants ( ('to breathe'); (pre-1918 spelling: )). There are a number of exceptions to the above vowel-reduction rules: • Vowels may not merge in foreign borrowings, particularly with unusual or recently borrowed words such as , 'radio'. In such words, unstressed may be pronounced as , regardless of context; unstressed does not merge with in initial position or after vowels, so word pairs like and , or and , differ in pronunciation. • Across certain word-final inflections, the reductions do not completely apply. For example, after soft or unpaired consonants, unstressed , and of a final syllable may be distinguished from each other. For example, ('residents') contrasts with both ('[about] a resident') and ('(of) a resident'). Also, ('he goes') and ('they go'). • If the vowel belongs to the conjunctions ('but') or ('then'), it is not reduced, even when unstressed.
Other changes Unstressed is generally pronounced as a lax (or
near-close) , e.g. ('man'). Between soft consonants, it becomes centralized to , as in ('to huddle'). Note a spelling irregularity in of the reflexive suffix : with a preceding in third-person present and a in infinitive, it is pronounced as , i.e. hard instead of with its soft counterpart, since , normally spelled with , is traditionally always hard. In other forms both pronunciations and (or and after vowels, spelled ) alternate for a speaker with some usual form-dependent preferences: in the outdated dialects, reflexive imperative verbs (such as , lit. "be afraid yourself") may be pronounced with instead of modern (and phonetically consistent) . In adverbial participles ending on or (with a stressed suffix), books on Russian standard pronunciation prescribe as the only correct variant. In weakly stressed positions, vowels may become voiceless between two voiceless consonants: ('exhibition'), ('because'). This may also happen in cases where only the following consonant is voiceless: ('skull').
Phonemic analysis Because of mergers of different phonemes in unstressed position, the assignment of a particular phone to a phoneme requires phonological analysis. There have been different approaches to this problem: • The Saint Petersburg phonology school assigns allophones to particular phonemes. For example, any is considered as a realization of . • The Moscow phonology school uses an analysis with
morphophonemes (, singular ). It treats a given unstressed allophone as belonging to a particular morphophoneme depending on morphological alternations. For example, is analyzed as either or . To make a determination, one must seek out instances where an unstressed morpheme containing in one word is stressed in another word. Thus, because the word ('shafts') shows an alternation with ('shaft'), this instance of belongs to the morphophoneme . Meanwhile, ('oxen') alternates with ('ox'), showing that this instance of belongs to the morphophoneme . If there are no alternations between stressed and unstressed syllables for a particular morpheme, then no assignment is made, and existence of an
archiphoneme is postulated. For example, the word ('dog') is analysed as , where is an archiphoneme. • Some linguists prefer to avoid making the decision. Their terminology includes strong vowel phonemes (the five) for stressed vowels plus several weak phonemes for unstressed vowels: thus, represents the weak phoneme , which contrasts with other weak phonemes, but not with strong ones.
Diphthongs Russian diphthongs all end in a non-syllabic , an allophone of and the only
semivowel in Russian. In all contexts other than after a vowel, is considered an approximant consonant. Phonological descriptions of may also classify it as a consonant even in the coda. In such descriptions, Russian has no diphthongs. The first part of diphthongs is subject to the same allophony as their constituent vowels. Examples of words with diphthongs: ('egg'), ('her' dat.), ('effective'). , written or , is a common inflexional affix of adjectives, participles, and nouns, where it is often unstressed; at normal conversational speed, such unstressed endings may be monophthongized to . When stressed, this affix is spelled and pronounced . Unstressed may be pronounced (as if spelled ) in free variation with . In adjectives ending in , traditional Moscow norm prescribed the pronunciation (as if spelled ), but now those adjectives are usually pronounced according to the spelling, thus . The same can be said about verbs ending in . ==Consonants==
