⟨Ҕ⟩ is the fifth letter of the Yakut alphabet, placed between ⟨Г⟩ and ⟨Д⟩. It was formerly also the seventh letter of the Abkhaz alphabet, placed between the digraphs ⟨Гә⟩ and ⟨Ҕь⟩; it was replaced by the letter ⟨Ӷ⟩.
Ge with middle hook was also used in the Chuvash language, in Ivan Yakovlev's initial 47-letter alphabet.
