Greek Capital Letter Epsilon with Tonos

The Greek Capital Letter Epsilon with Tonos at U+0388 is an uppercase Greek vowel letter carrying the Modern Greek stress mark, used for stressed initial or all-capital epsilon sounds. It belongs to the Greek and Coptic block and represents capital epsilon with a tonos accent, corresponding to the lowercase έ. Its everyday use is in Modern Greek words where the stressed syllable falls on an epsilon and the word is capitalized or begins a sentence, such as Έλληνας, “Greek man,” or Έλενα, the name Elena. In fully uppercase Greek, it appears in headings, signs, titles, forms, and newspapers when accent marks are retained: ΈΝΑ can show the stressed vowel in “one.” The letter is also used in Greek language teaching, dictionaries, and transliteration-aware text processing to distinguish accented Modern Greek spelling from plain Ε. It is not a separate alphabet letter in pronunciation; the tonos marks stress, while epsilon itself is pronounced like the vowel in Modern Greek words such as σε.
