Latin epsilon or open E (majuscule: Ɛ, minuscule: ɛ) is a letter of the extended Latin alphabet, based on the lowercase of the Greek letter epsilon (ε). It was introduced in the 16th century by Gian Giorgio Trissino^[1] to represent the pronunciation of the "open e" (the letter e pronounced as the open-mid front unrounded vowel) in the Italian language; this use of the letter has since become the standard in IPA notation^[1] (see § Use in phonetic alphabets, below). Since the 20th century, the letter also occurs in the orthographies of many Niger–Congo and Nilo-Saharan languages, such as Ewe, Akan, Lingala, Dinka and Maasai, for the vowel [ɛ] or [e̙], and is included in the African reference alphabet.

In the Berber Latin alphabet used in Algerian Berber school books,^[2] and before that proposed by the French institute INALCO, it represents a voiced pharyngeal fricative [ʕ]. Some authors use ƹayin ⟨ƹ⟩ instead;^{[citation needed]} both letters are similar in shape with the Arabic ʿayn ⟨ع⟩.

Use in phonetic alphabets

The International Phonetic Alphabet (IPA) uses various forms of the Latin epsilon:

U+025B ɛ LATIN SMALL LETTER OPEN E represents the open-mid front unrounded vowel
U+025D ɝ LATIN SMALL LETTER REVERSED OPEN E WITH HOOK represents the rhotacized open-mid central vowel
U+025E ɞ LATIN SMALL LETTER CLOSED REVERSED OPEN E represents the open-mid central rounded vowel (shown as U+029A ʚ LATIN SMALL LETTER CLOSED OPEN E on the 1993 IPA chart)

The Uralic Phonetic Alphabet uses various forms of the Latin epsilon:^[3]

Latin epsilon is called "Open E" in Unicode.^[4]
