Yus

**Little yus** (Ѧ, ѧ; italics: *Ѧ, ѧ*) and **big yus** (Ѫ, ѫ; italics: *Ѫ, ѫ*), or **jus**, are letters of the Cyrillic script representing two Common Slavonic nasal vowels in the early Cyrillic and Glagolitic alphabets. Each can occur in iotated form (Ѩ ѩ, Ѭ ѭ), formed as ligatures with the decimal i (І). Other yus letters are **blended yus**(Ꙛ ꙛ), **closed little yus** (Ꙙ ꙙ) and **iotated closed little yus** (Ꙝ ꙝ).

Phonetically, little yus represents a nasalized front vowel, possibly [ɛ̃], while big yus represents a nasalized back vowel, such as IPA [ɔ̃]. This is also suggested by the appearance of each as a 'stacked' digraph of 'Am' and 'om' respectively.

The names of the letters do not imply capitalization, as both little and big yus exist in majuscule and minuscule variants.

## Disappearance

All modern Slavic languages that use the Cyrillic alphabet have lost the nasal vowels (at least in their standard varieties), making Yus unnecessary.

### In Bulgarian and Macedonian

Big Yus was a part of the Bulgarian alphabet until 1945. However by then, in the eastern dialects, the back nasal was pronounced the same way as ъ [ɤ]. Because the language is based mainly on them, the western pronunciations were deemed unliterary, and the letter was gone.

There were some Bulgarian and Macedonian dialects spoken around Thessaloniki and Kastoria in northern Greece (Kostur dialect, Solun dialect) that still preserve a nasal pronunciation e.g. [ˈkɤ̃de ˈɡrẽdeʃ ˈmilo ˈt͡ʃẽdo] (Къде гредеш, мило чедо?; "Where are you going, dear child?"), which could be spelled pre-reform as "Кѫдѣ грѧдешъ, мило чѧдо?" with big and little yus.

On a visit to Razlog, in Bulgaria's Pirin Macedonia, in 1955, the Russian dialectologist Samuil Bernstein noticed that the nasal pronunciation of words like [ˈrɤ̃ka] (hand), [ˈt͡ʃẽdo] (child) could still be heard from some of the older women of the village. To the younger people, the pronunciation was completely alien; they would think that the old ladies were speaking Modern Greek.

### In Russian

In Russia, the little Yus came to be pronounced as an iotated /ja/ (я) in the middle or at the end of a word and therefore came to represent that sound also elsewhere;[*citation needed*] the modern letter я is an adaptation of its cursive form of the 17th century, enshrined by the typographical reform of 1708. (That is also why я in Russian often corresponds to nasalized *ę* in Polish; cf. Russian пять; Polish *pięć*.)

### In Polish

In Polish, which is a Slavic language written in the Latin alphabet, the letter *Ę ę*has the phonetic value of little Yus, and *Ą ą* has that of big Yus. The iotated forms are written *ię/ję* and *ią/ją*, respectively. However, the phonemes written *ę* and *ą*are not directly descended from those represented by little and big yus but developed after the original nasals merged in Polish and then diverged again. (Kashubian, the closest language to Polish, uses the letter *ã* instead of *ę*.)

### In Romanian

Little and big yuses can also be found in the Romanian Cyrillic alphabet, used until 1862. Little Yus was used for /ja/ and big Yus for unknown vowels, transcribed in later Romanian as  /ɨ/ and /ə/. Now Romanian uses the Latin alphabet and /ɨ/ is written Îî or Ââ. /ə/ is written as Ăă.

One of the first transcriptions of the big yus as î in Romanian is found in Samuel Klain, Acathist, Sibii, 1801.

### In Slovak

Little yus in the Slovak alphabet has been substituted by *a* (*desať*, *načať*), *e*(*plesať*), iotated *ia* (*žiadať*, *kliatba*, *mesiac*), *ie* (*bdieť*) and *ä* in several cases (*pamäť*, *päť*, *svätý*). Big yus is transliterated and pronounced as *u*, or accented *ú*(*budeš*, *muž*, *mučeník*, *ruka*, *navyknúť*, *pristúpiť*, *púť*, *usnúť*). Iotated, and closed iotated form of little yus occur as *ja* (e.g. *jazyk*, *svoja*, *javiť*, *jasle*).

### In Ruthenian

In Ruthenian language, little yus was used to transcribe the sound *ja* (as in руска(ѧ) мова ("Ruthenian language") or ѧзыкъ ("language")). This evolved into and corresponded with the letter я in the descendant languages of Belarusian, Ukrainian, and Rusyn.
