Mizrahi (Oriental) Hebrew is actually a collection of dialects spoken liturgically by Jews in various parts of the Arab and Islamic world. It was derived from the old Arabic language, and in some cases influenced by Sephardi Hebrew. The same claim is sometimes made for Yemenite Hebrew or "Temanit", which differs from other Mizrahi dialects by having a radically different vowel system, and distinguishing between different diacritically marked consonants that are pronounced identically in other dialects (for example gimel and "ghimel".)
