Iotated E
archaic Cyrillic letter iotified E

Iotated E or Iotated Ukrainian Ye also known as Iye(Ѥ ѥ) is a letter of the Cyrillic script, and it is used in the Church Slavonic language and Early Cyrillic.
History
Iotated E has no equivalent in the Glagolitic alphabet, and probably originated as a ligature of ⟨і⟩ and ⟨е⟩ to represent the sounds [je] or [jɛ].
Usage
Iotated E is found in some of the very oldest examples of Cyrillic writing, such as the tenth-century Mostich inscription or the Codex Suprasliensis, whereas in others, such as the Enina Apostle or Undol'skij Fragments, it is not present at all. It is plentifully attested in medieval manuscripts of both South Slavic and East Slavic provenance, co-existing with ⟨є⟩, which fulfils the same function. Orthographic practice nevertheless varies: some manuscripts use all three characters, some ⟨е⟩ and ⟨ѥ⟩, some ⟨е⟩ and ⟨є⟩, and some only ⟨е⟩.
Among the Eastern Slavs ⟨ѥ⟩ fell into disuse after the end of the fourteenth century, and it is not therefore represented in printed books from this area, or in modern Church Slavonic. In the South, however, it survived, and was used in the first Serbian printed book, the Octoechos (Oktoih prvoglasnik) of 1474, and appears in the Serbian abecedarium printed in Venice in 1597; its position in the alphabet in this book is between ⟨ю⟩ and ⟨ѯ⟩. It continued to be used in both manuscript and printed material throughout the sixteenth and seventeenth centuries, but it no longer appears in the alphabet in M. Karaman's abecedarium of 1753. In certain orthographical variants of Bulgarian, it can be found at least up to the middle of the 19th century. Bulgarian variants from the 1800s often include the letter as a ligature of ⟨І⟩ and ⟨Е⟩, rather than ⟨Є⟩.
This brief starts where responsible research should: with the source description of “Iotated E” as archaic Cyrillic letter iotified E. 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 archaic Cyrillic letter iotified E. 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 Jul 20, 2026. The linked authority identifier is Q424885. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1474, 1597 and 1753.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
