Omega (Cyrillic)
letter used in the early Cyrillic alphabet
Omega (Ѡ ѡ; italics: Ѡ ѡ) is a letter used in the early Cyrillic alphabet. Its name and capital form are derived directly from the Greek letter Omega ⟨Ω ω⟩.
In some forms it looks similar to the letter We.
Unlike Greek, the Slavic languages had only a single /ɔ/ sound, so Omega was little used compared to the letter O (О о), descended from the Greek letter Omicron. In the older ustav writing, Omega was used mainly for its numeric value of 800, and rarely appeared even in Greek words. In later semi-ustav manuscripts it was used for decorative purposes, along with the broad version ⟨Ꙍ ꙍ⟩ as well as the Broad On ⟨Ѻ ѻ⟩.
Modern Church Slavonic has developed strict rules for the use of these letterforms.
Another variation of omega is the ornate or beautiful omega, used as an interjection, "O!". It is represented in Unicode 5.1 by the misnamed character omega with titlo ⟨Ѽ ѽ⟩. It descends from the Greek omega with the smooth breathing (psili) and circumflex (perispomeni) diacritical marks ⟨Ὦ ὦ⟩, also used in the corresponding exclamation in ancient Greek.
This brief starts where responsible research should: with the source description of “Omega (Cyrillic)” as letter used in the early Cyrillic alphabet. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as letter used in the early Cyrillic alphabet. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Apr 9, 2026. The linked authority identifier is Q424863. None of the 0 selected statements returned an explicit reference.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
