O-hook

O-hook (Ҩ ҩ; italics: Ҩ ҩ ) is a letter of the Cyrillic script. It is derived from the initial form of the Arabic letter hāʾ, $⟨هـ⟩$. In the Unicode text-encoding standard, this letter is called "Abkhazian Ha". Its form bears some similarities to the Greek letter Theta (Θ θ/ϑ). In English, O-hook is commonly romanized using the Ọ|Latin letter O with dot below (Ọ ọ) but its ISO 9 transliteration is the Ò|Latin letter O with grave accent (Ò ò).

O-hook is used in the alphabet of the Abkhaz language where it represents the labial-palatal approximant, the sound of $⟨ui⟩$ in French "". It is placed between Ы and Џ in the alphabet.
