Nogai vowels include two unique letters not in Russian: Ө (front rounded ö-vowel) and Ү (close front rounded ü-vowel). These front-rounded vowels participate in Nogai vowel harmony alongside the standard vowels Е and И.
Nogai vowel harmony divides vocabulary into front-vowel words (containing Ө, Ү, Е, И) and back-vowel words (А, О, У, Ы). Grammatical suffixes must agree with the vowel class of the root — a fundamental feature shared across the Turkic language family.
Nogai uses three unique consonant letters beyond Russian Cyrillic: Ғ (voiced uvular fricative gh-sound), Қ (uvular stop q-sound), and Нъ (velar nasal ng digraph). These encode Turkic phonemes common in Kipchak languages.
The uvular consonants Ғ and Қ reflect Mongol and Arabic influence on Nogai phonology — these sounds appear in many words inherited from the era of the Golden Horde and its successors. The Нъ digraph represents the velar nasal that appears in Turkic grammatical endings.
The unique letters of the Nogai Cyrillic alphabet: Ғ/ғ (uvular gh-sound), Қ/қ (uvular q-sound), Нъ (velar ng digraph), Ө/ө (front rounded ö), and Ү/ү (close front rounded ü).
The Нъ digraph (using the hard sign ъ) is characteristic of Nogai orthography for encoding the ng-nasal. Some Nogai texts use the single letter Ҥ instead, but the digraph form is more commonly seen. The uvular consonants Ғ and Қ are shared with Karakalpak and Kazakh Cyrillic alphabets.
Nogai uses Arabic numerals (0–9) in modern writing. The native Nogai number words: нол (0), бир (1), эки (2), уьш (3), дёрт (4), бес (5), алты (6), йети (7), сегиз (8), тоғыз (9).
The number words reveal Nogai phonology: тоғыз (nine) uses the unique consonant Ғ, demonstrating its place in everyday vocabulary. The shared Turkic roots бир (one), алты (six), and сегиз (eight) are recognisable across the entire Turkic family.

The Nogai Cyrillic alphabet integrates its unique letters (Ғ, Қ, Нъ, Ө, Ү) into the standard Russian Cyrillic sequence. This orthography was standardised during the Soviet era and remains in use in Dagestan and other regions of Russia where Nogai is spoken.
