Soft sign
The soft sign (⟨ь⟩) in most positions acts like a “silent front vowel” and indicates that the preceding consonant is palatalized (except for always-hard ж, ш, ц) and the following vowel (if present) is iotated (including ⟨ьо⟩ in loans). This is important as palatalization is phonemic in Russian. For example, брат [brat] (‘brother’) contrasts with брать [bratʲ] (‘to take’). The original pronunciation of the soft sign, lost by 1400 at the latest, was that of a very short fronted reduced vowel /ĭ/ but likely pronounced [ɪ] or [jɪ]. There are still some remnants of this ancient reading in modern Russian, e.g. in co-existing versions of the same name, read and written differently, such as Марья and Мария (‘Mary’).
When applied after stem-final always-soft (ч, щ, but not й) or always-hard (ж, ш, but not ц) consonants, the soft sign does not alter pronunciation, but has grammatical significance:
- the feminine marker for singular nouns in the nominative and accusative; e.g. тушь (‘India ink’, feminine) cf. туш (‘flourish after a toast’, masculine) – both pronounced [tuʂ];
- the imperative mood for some verbs;
- the infinitives of some verbs (with -чь ending);
- the second person for non-past verbs (with -шь ending);
- some adverbs and particles.
- Treatment of foreign sounds
- Because Russian borrows terms from other languages, there are various conventions for sounds not present in Russian.
- For example, while Russian has no [h], there are a number of common words (particularly proper nouns) borrowed from languages like English and German that contain such a sound in the original language. In well-established terms, such as галлюцинация [ɡəlʲʊtsɨˈnatsɨjə] (‘hallucination’), this is written with ⟨г⟩ and pronounced with /ɡ/, while newer terms use ⟨х⟩, pronounced with /x/, such as хобби [ˈxobʲɪ] (‘hobby’).
- Similarly, words originally with [θ] in their source language are either pronounced with /t(ʲ)/, as in the name Тельма (‘Thelma’) or, if borrowed early enough, with /f(ʲ)/ or /v(ʲ)/, as in the names Фёдор (‘Theodore’) and Матве́й (‘Matthew’).
- For the [d͡ʒ] affricate, which is common in the Asian countries that were part of the Russian Empire and the USSR, the letter combination ⟨дж⟩ is used: this is often transliterated into English either as ⟨dzh⟩ or the Dutch form ⟨dj⟩.
- Numeric values
- The numerical values correspond to the Greek numerals, with ⟨ѕ⟩ being used for digamma, ⟨ч⟩ for koppa, and ⟨ц⟩ for sampi. The system was abandoned for secular purposes in 1708, after a transitional period of a century or so; it continues to be used in Church Slavonic, while general Russian texts use Indo-Arabic numerals and Roman numerals.
- Diacritics
- The Cyrillic alphabet and Russian spelling generally employ fewer diacritics than those used in other European languages written with the Latin alphabet. The only diacritic, in the proper sense, is the acute accent ⟨◌́⟩ (Russian: знак ударения ‘mark of stress’), which marks stress on a vowel, as it is done in Spanish and Greek. (Unicode has no code points for the accented letters; they are instead produced by suffixing the unaccented letter with U+0301 ◌́ COMBINING ACUTE ACCENT.) Although Russian word stress is often unpredictable and can fall on different syllables in different forms of the same word, the diacritic accent is used only in dictionaries, children’s books, resources for foreign-language learners, the defining entry (in bold) in articles on Russian Wikipedia, or on minimal pairs distinguished only by stress (for instance, за́мок ‘castle’ vs. замо́к ‘lock’). Rarely, it is also used to specify the stress in uncommon foreign words, and in poems with unusual stress used to fit the meter.
- The letter ⟨ё⟩ is a special variant of the letter ⟨е⟩, which is not always distinguished in written Russian, but the umlaut-like sign has no other uses. Stress on this letter is never marked with a diacritic, as it is always stressed (except in some compounds and loanwords).
- Both ⟨ё⟩ and the letter ⟨й⟩ have completely separated from ⟨е⟩ and ⟨и⟩. ⟨Й⟩ has been used since the 16th century (except that it was removed in 1708, but reinstated in 1735). Since then, its usage has been mandatory. It was formerly considered a diacriticized letter, but in the 20th century, it came to be considered a separate letter of the Russian alphabet. It was classified as a “semivowel” by 19th- and 20th-century grammarians but since the 1970s, it has been considered a consonant letter.
