U+042B "Ы" Cyrillic Capital Letter Yeru Unicode Character

Unicode Version 17.0

Ы

U+042B "Ы" Cyrillic Capital Letter Yeru is a distinctive letter in the Cyrillic script primarily used in Russian, Belarusian, and some other Slavic languages. It represents a hard, unrounded vowel sound, often described as a combination or diphthong of [i] and a back vowel, with no direct equivalent in English. Historically derived from the digraph of the letters "ъ" and "i" in older Cyrillic orthography, "Ы" is considered a separate vowel that requires a specific mouth position, with the tongue pulled back and slightly raised, making it a notable challenge for learners of Russian. In modern Russian, it appears in many common words and is paired with its lowercase counterpart "ы".
