Livonian has an exceptionally rich vowel system with 15 vowel letters: A, Ā, Ä, Ǟ, E, Ē, I, Ī, O, Ō, Ȱ, Ö, Ȫ, U, Ū. For each of the basic vowels A, E, I, O, U, Livonian distinguishes short and long versions (marked with macron), and in some cases additional vowel qualities.
Three Livonian vowel letters are unique among all world writing systems: Ǟ (long Ä with macron), Ȱ (O with dot and macron — the stød or broken tone long O), and Ȫ (Ö with macron — long rounded front vowel). The stød (stōʻd) is a distinctive laryngeal feature — a creaky voice or tone break — that Livonian shares with Latvian but not with other Finnic languages [3]. The University of Latvia has studied this rare phonological feature in depth.
Livonian has 21 consonant letters including three palatalised consonants unique to Livonian and Latvian: Ļ (palatalised L), Ņ (palatalised N), and Ŗ (palatalised R). These palatalised letters are shared with Latvian — borrowed into the Livonian orthography system due to historical Latvian-Livonian contact.
The letter Ŗ (R with cedilla — palatalised R) is particularly unusual: it marks a soft, palatalised R found in Latvian that Livonian adopted into its own phonology through centuries of contact with Latvian speakers [2]. This borrowed palatalisation feature makes Livonian phonologically distinctive among Finnic languages, which do not normally have palatalised lateral and rhotic consonants.
Livonian has 14 special characters beyond basic Latin: Ā, Ǟ, Ē, Ī, Ļ, Ņ, Ō, Ȱ, Ȫ, Ŗ, Š, Ū, Ž, and Ä. Three of these — Ǟ, Ȱ, Ȫ — are found in virtually no other writing system, making the Livonian orthography orthographically one of a kind.
The Livonian Heritage Foundation [1] has worked to ensure these unique characters are properly supported in Unicode and digital typography, making it possible to write Livonian correctly on modern devices. The Latvian Language Agency [2] and the University of Latvia [3] have produced digital resources supporting Livonian orthography, including fonts and keyboard layouts for the unique Livonian characters.
Livonian uses Arabic numerals (0–9). The native Livonian number words: nūļ (0), ikš (1), kakš (2), kuolm (3), nēļa (4), vīž (5), kuž (6), seis (7), kōdõks (8), īdõks (9).
Livonian number words reveal the language's Baltic Finnic ancestry. Words like kakš (two, cf. Estonian kaks, Finnish kaksi) and kuolm (three, cf. Estonian kolm) are clearly Uralic cognates, while distinctive Livonian phonological features (like the vowel contrasts and stød) have shaped these inherited words into their unique Livonian forms. The University of Latvia [3] has documented Livonian numerals in its lexicographic studies of the language.
A complete view of all 36 Livonian letters in alphabetical order. The alphabet is one of the most distinctive in Europe, with many unique diacritic forms that reflect Livonian's exceptional vowel system and its historical contact with Latvian.
The Livonian Heritage Foundation [1] actively promotes this unique alphabet through teaching materials, publications, and cultural events along the historic Livonian Coast (Līvõd rānda). The Latvian Language Agency [2] and University of Latvia [3] support scholarly documentation that preserves the full Livonian alphabet for future learners and researchers.
