Võro has 9 vowel letters including four unique diacritics: Ä (front open vowel), Õ (back unrounded vowel), Ö (front rounded vowel), and Ü (front close rounded vowel). The letter Õ — marking a vowel absent from Finnish and most European languages — is a defining feature of the Estonian Finnic branch.
Võro preserves a three-way vowel quantity distinction — short, long, and overlong — that is shared with standard Estonian but applied in distinct phonological environments. Võro also exhibits vowel alternation patterns that differ from standard Estonian, reflecting distinct sound changes in the southern Estonian dialect area.
Võro consonants include two sibilants with diacritics: Š (postalveolar sh-sound) and Ž (postalveolar zh-sound), primarily appearing in loanwords from Russian and German. The core consonants B, D, F, G, H, J, K, L, M, N, P, R, S, T, and V use standard Latin letters without diacritics.
A key Võro consonant feature is the preservation of word-final consonants — unlike standard Estonian, Võro retains these consonants in positions where northern Estonian has simplified them. Consonant gradation, the Uralic process of alternating strong and weak consonant grades, also operates in Võro following patterns distinct from standard Estonian.
The 6 unique letters of the Võro alphabet: Š/š (sh-sound), Ž/ž (zh-sound), Ä/ä (front open vowel), Õ/õ (back unrounded vowel), Ö/ö (front rounded vowel), and Ü/ü (front close rounded vowel). All six extend the core Latin A–Z set used in Võro writing.
The letter Õ (O with a tilde) is the most distinctive — it represents the back unrounded mid vowel, a sound specific to Estonian and South Estonian absent from Finnish, Latvian, and most European languages. Õ was formally introduced into Estonian orthography in the nineteenth century and is retained in the Võro standardised writing system.
Võro uses Arabic numerals (0–9) in modern writing. The native Võro number words: null (0), üts (1), katõ (2), kolm (3), neli (4), viis (5), kuus (6), sõidsa (7), katõssa (8), ühesä (9).
Võro number words reveal archaic Finnic forms distinct from standard Estonian — üts (one) and katõ (two) contrast with standard Estonian üks and kaks, reflecting distinct sound changes in the southern Võro dialect. The characteristic Õ vowel appears in katõ (two) and katõssa (eight), illustrating its integration into core vocabulary.
A complete view of all 30 Võro letters in alphabetical order, including the six unique diacritics Š, Ž, Ä, Õ, Ö, and Ü. The alphabet was standardised by the Võro Institute for use in Võro publications, educational materials, and digital resources.
The Võro alphabet follows standard Estonian ordering conventions — diacritic vowels Ä, Ö, Õ, Ü are placed after Z at the end of the alphabet, while Š and Ž appear after S and Z respectively. This ordering was adopted for compatibility with existing Estonian library and database systems used across Estonia.
