In Yevanic writing, vowels were represented primarily through matres lectionis — consonant letters used as vowel markers. The four letters Aleph (א /ʔ/a), He (ה /h/), Vav (ו /v/ or /u/o), and Yod (י /j/ or /i/e) served dual roles as both consonants and vowel indicators.
Vowel diacritics (nikud) were used in educational texts and prayer books but were typically omitted in everyday writing. This unvowelized Hebrew-script writing required readers to know the language to interpret the text correctly.
Yevanic used all 22 letters of the standard Hebrew alphabet [1], with some letters adapting to represent Greek sounds not present in traditional Hebrew. The dagesh (a dot written inside a letter) distinguished the plosive and fricative versions of Beth (ב), Kaf (כ), and Pe (פ) — so Beth without dagesh = /v/, with dagesh = /b/.
Since Yevanic is a form of Greek, some of its Greek consonants do not exist in standard Hebrew phonology. Gimel (ג) and other letters were occasionally used to represent Greek sounds like /dʒ/ or to distinguish Yevanic words from Hebrew-origin words.
Yevanic texts in prayer books and educational settings used Hebrew vowel diacritics (nikud) to mark vowel sounds [1]. The most common diacritics include the Sheva (ְ), Kamats (ָ), Patah (ַ), Tsere (ֵ), Hiriq (ִ), and Holam (ֹ).
The dagesh (ּ) was used to distinguish the hard/plosive pronunciation of bet (בּ /b/), kaf (כּ /k/), and pe (פּ /p/) from their soft/fricative forms (ב /v/, כ /x/, פ /f/). In Yevanic, the shin dot (ׁ) and sin dot (ׂ) distinguish shin /ʃ/ from sin /s/ in the letter ש.
Traditional Yevanic texts used Hebrew letters as numerals, with each letter having a corresponding numerical value (Gematria): Aleph=1, Beth=2, Gimel=3, and so on up to Qof=100, Resh=200, Shin=300, Tav=400. In modern contexts, Arabic numerals (1–9) are standard.
Five Hebrew letters have special final (sofit) forms used exclusively when the letter appears at the end of a word. These are Kaf sofit (ך), Mem sofit (ם), Nun sofit (ן), Pe sofit (ף), and Tsadi sofit (ץ). Yevanic writing used these final forms as in standard Hebrew orthography.
