U+042A "Ъ" Cyrillic Capital Letter Hard Sign Unicode Character

Unicode Version 17.0

Ъ

U+042A "Ъ" Cyrillic Capital Letter Hard Sign is a letter in the Cyrillic script used primarily in Russian and Bulgarian, where it represents the hard sign, a letter that historically indicated a very short vowel sound but in modern Russian primarily functions as a separator that prevents palatalization of the preceding consonant before a following soft vowel. In Bulgarian, it retains its role as a distinct vowel sound, the mid back unrounded vowel /ɤ/, making it a common and essential letter in that language. Unlike most Cyrillic letters, it has no inherent phonetic value in Russian and is never pronounced as a consonant or vowel, instead serving as a grammatical marker, typically found between a prefix ending in a hard consonant and a root beginning with a soft vowel. Its uppercase form visually resembles a large, bold letter with a straight vertical stem and a closed top, distinguishing it from the soft sign, the similar but smaller and more curved character.
