Csángó uses the same 14 vowel letters as standard Hungarian, arranged in short/long pairs: A/Á, E/É, I/Í, O/Ó, Ö/Ő, U/Ú, Ü/Ű, including the double-acute vowels Ő and Ű. In speech, the Csángó dialect preserves some older vowel qualities lost in the modern standard [1].
The Romanian Cultural Institute [1] documents Csángó speech and culture, and UiT The Arctic University [2] studies these conservative vowel features in the context of the wider Hungarian dialect landscape.
Csángó uses the same single-letter consonants as standard Hungarian: B, C, D, F, G, H, J, K, L, M, N, P, R, S, T, V, Z. As in Hungarian, the letter S represents "sh" while SZ represents plain "s" [1].
The Romanian Cultural Institute [1] and UiT The Arctic University [2] document how the Csángó consonant system, shaped by centuries of contact with Romanian, still follows the Hungarian writing conventions.
Csángó writing uses the Hungarian digraphs CS, GY, LY, NY, SZ, TY and ZS, each treated as a single letter as in standard Hungarian orthography [1].
Because Csángó is written with Hungarian orthography, these digraphs work exactly as they do in the standard language. The Romanian Cultural Institute [1] and ELAR [3] document Csángó texts using this Hungarian-based writing system.
Csángó uses Arabic numerals (0–9). As a Hungarian dialect, its number words match standard Hungarian: nulla (0), egy (1), kettő (2), három (3), négy (4), öt (5), hat (6), hét (7), nyolc (8), kilenc (9).
These numerals preserve the same deep Uralic roots as standard Hungarian — words like három (3) and öt (5) go back to shared Ugric ancestors. UiT The Arctic University [2] studies these features in the Csángó dialect within its comparative Uralic research.
The complete Csángó alphabet, following Hungarian Latin orthography, including the accented vowels and the digraphs treated as single letters.
The Romanian Cultural Institute [1], UiT The Arctic University [2] and ELAR [3] collectively document the Csángó dialect and its Hungarian-based writing, preserving this archaic Hungarian variety of Romania.
