Fante translation of the Book of Mormon; note the use of the Latin epsilon in the word N'AHYƐMU.

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 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 (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, and before that proposed by the French institute INALCO, it represents a voiced pharyngeal fricative [ʕ]. Some authors use ƹayin ⟨ƹ⟩ instead; 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:

• U+1D08 ᴈ LATIN SMALL LETTER TURNED OPEN E
• U+1D4B ᵋ MODIFIER LETTER SMALL OPEN E
• U+1D4C ᵌ MODIFIER LETTER SMALL TURNED OPEN E
