Ossetic has 11 vowel letters — the 10 standard Russian vowels plus the unique Ӕ/ӕ (U+04D4/U+04D5), which represents the open-mid front unrounded vowel /æ/ (like "a" in "cat"). This letter is absent from all other Cyrillic scripts and is the single most distinctive feature of the Ossetic alphabet. Ossetic vowel harmony and the /æ/ sound reflect the language's ancient Eastern Iranian roots.
Ossetic uses the 21 consonant letters of Russian Cyrillic. Beyond these monographic consonants, Ossetic represents its distinctive ejective consonants using digraphs — two-letter combinations formed with a base consonant + hard sign (Ъ/ъ): гъ (/ɣ/), дж (/dʒ/), дз (/dz/), къ (/kʼ/), пъ (/pʼ/), тъ (/tʼ/), хъ (/qʰ/), цъ (/tsʼ/), чъ (/tʃʼ/). These ejectives are a Caucasian areal feature shared with Georgian and Armenian.
Ossetic's most distinctive phonological feature is its 9 ejective consonant digraphs, each written as a base letter + hard sign (Ъ/ъ). Ejectives are sounds produced with a glottalic airstream — a sharp, popped quality. This series (гъ, дж, дз, къ, пъ, тъ, хъ, цъ, чъ) is a Caucasian areal feature: Ossetic acquired ejective consonants through contact with neighbouring languages such as Georgian and the Northeast Caucasian languages, making it unique among all Iranian languages.
Ossetic uses the hard sign (Ъ/ъ) and soft sign (Ь/ь) from Russian Cyrillic. Uniquely in Ossetic, the hard sign (ъ) also serves as the second element of every ejective consonant digraph (гъ, дж, дз, къ, пъ, тъ, хъ, цъ, чъ), making it one of the highest-frequency letters in native Ossetic vocabulary. The soft sign (ь) palatalizes preceding consonants and appears mainly in Russian loanwords.
The complete Ossetic alphabet with all 34 base letters in both uppercase and lowercase forms — from А (a) to Я (ya), including the unique Ӕ/ӕ that sets the Ossetic Cyrillic script apart from all other Cyrillic alphabets. The ejective digraphs (гъ, дж, дз, etc.) are formed from letters already present in this base alphabet.
Ossetic uses standard Arabic numerals (0–9), the same as Russian. The native Ossetic number words are distinct from Russian: иу (1), дыууæ (2), æртæ (3), цыппæр (4), фондз (5), æхсæз (6), авд (7), æст (8), фараст (9) — reflecting the Eastern Iranian core vocabulary of the language.
Ossetic texts use standard Cyrillic punctuation following the Russian convention, including guillemets (« ») as the standard quotation marks. All standard Western punctuation marks (., , ; : ? !) are used as in Russian typography.
