Adyghe has only 3 native vowels: А (long open /aː/), Э (short central /ɐ/), and Ы (schwa /ə/) — making it one of the languages with the fewest native vowels on Earth. Additional vowels (Е, И, О, У, Ю, Я) appear only in Russian loanwords.
This tiny vowel inventory is a hallmark of the entire Northwest Caucasian language family. Adyghe compensates with an extraordinarily rich consonant system where labialized consonants (written with у) and ejective consonants (marked by Ӏ) carry most of the phonological weight.
Adyghe boasts one of the world's largest consonant inventories. The system features ejective consonants marked by the palochka Ӏ (Пӏ, Тӏ, Кӏ, Цӏ, Чӏ, Шӏ, Лӏ, Фӏ), labialized consonants using у (Гу, Ку, Хъу, Цу, etc.), the voiceless lateral fricative Лъ (a "hissing L"), and pharyngeal Хӏ — sounds with no equivalent in English or Russian.
The palochka Ӏ (U+04C0 uppercase, U+04CF lowercase) is a dedicated Unicode character used across Northwest Caucasian languages. Each Ӏ-marked consonant (e.g. Пӏ = ejective P) represents a completely different phoneme from its plain counterpart (П = regular P).
In Adyghe, Ъ and Ь serve as phonemic consonant modifiers: Ъ creates pharyngealized variants (Гъ, Жъ, Шъ, Хъ), while Ь creates palatalized variants (Гь, Жь, Хь, Шь). Unlike in Russian, these are not grammatical signs but integral consonant-modifying elements that create distinct Adyghe phonemes.
The complete Adyghe alphabet in official order, encompassing all 66 letters (base letters plus digraphs and trigraphs) that together represent the full phonological system of the West Circassian language.
Adyghe uses standard Arabic numerals (0–9) for writing numbers, following Cyrillic orthographic conventions.
Adyghe uses standard Cyrillic punctuation including guillemets (« ») as quotation marks, in line with Russian typographic conventions adopted for Adyghe writing.
