էօ

Formed by analogy with իւ (iw) using the two dialectological letters for mid vowels.

• IPA^(key): [œ]

էօ • (ēō)

1. A letter formerly used in Armenian dialectology, nowadays usually written as օ̈ (ö). Represents the open-mid front rounded vowel: [œ]. Transliterated as ö.

Outside of dialectology, this letter combination is also used in traditional Armenian orthography to represent the [œ] sound in borrowings from Turkic and other languages with [œ] and [ø]-like sounds; for example, Քարակէօզեան (Kʿarakēōzean), Քէօշկէրեան (Kʿēōškērean), էօտ աղաճը (ēōt ałačə), Էօժէնի (Ēōžēni), Քէօլն (Kʿēōln).
