Latin epsilon oropen E (majuscule:Ɛ, minuscule:ɛ) is a letter of the extendedLatin alphabet, based on thelowercase of theGreek letterepsilon (ε). It was introduced in the 16th century byGian Giorgio Trissino[1] to represent the pronunciation of the "open e" (the lettere pronounced as theopen-mid front unrounded vowel) in theItalian language; this use of the letter has since become the standard inIPA notation[1](see§ Use in phonetic alphabets below). Since the 20th century, the letter also occurs in the orthographies of manyNiger–Congo andNilo-Saharan languages, such asEwe,Akan,Lingala,Dinka andMaasai, for the vowel[ɛ] or[e̙], and is included in theAfrican reference alphabet.
In theBerber Latin alphabet used in Algerian Berber school books,[2] and before that proposed by the French instituteINALCO, it represents avoiced pharyngeal fricative[ʕ]. Some authors useƹayin⟨ƹ⟩ instead;[citation needed] both letters are similar in shape with theArabic ʿayn⟨ع⟩.
