Latin epsilon or open e (majuscule, minuscule) is a letter of the extended Latin alphabet, based on the lowercase of the Greek letter epsilon (?). It occurs in the orthographies of many Niger-Congo languages, such as Ewe, Akan, and Lingala, and is included in the African reference alphabet.
In the Berber Latin alphabet currently used in Algerian Berber school books, and before that proposed by the French institute INALCO, it represents a voiced pharyngeal fricative [?]. Some authors use ?ayin ⟨?⟩ instead; both letters are similar in shape with the Arabic ?ayn ⟨?⟩.
The International Phonetic Alphabet (IPA) uses various forms of the Latin epsilon:

This is actually a Latin epsilon and should have been so called.
