Palatalization of consonants is marked with an acute accent (´) or apostrophe ('). In proper typography and in handwriting, the palatalisation mark does not extend above the cap height (except uppercase letters Ń, Ŕ, Ś, V́ etc.), and it is written above the letter if the letter has no ascender (ǵ, ḿ, ń, ṕ, ŕ, ś, v́ etc.) but written to the right of it otherwise (b’, d’, f’, h’, k’, l’, t’). In computing, it is not usually possible to enter these character combinations or to make them look esthetically pleasing with most common fonts, so the apostrophe is generally placed after the letter in all cases. This convention is followed in this article as well. Phonology Vowels Vowel harmony Võro has preserved the system of vowel harmony that was present in Proto-Finnic. This distinguishes it from Estonian and some other Finnic languages, which have lost it. The vowel harmony system distinguishes front, back and neutral vowels, much like the system found in Finnish. A word cannot contain both front and back vowels; suffixes automatically adapt the backness of the vowels depending on the type of vowels found in the word it is attached to. Neutral vowels can be combined with either type of vowel, although a word that contains only neutral vowels has front vowel harmony. The only neutral vowel is i, like in Votic but unlike Finnish and Karelian, where e is also neutral. The vowel ɨ (in the Võro orthography written with õ or y, see Orthography section) is considered a back vowel for harmony purposes, but does not participate in harmony itself, as it does not occur in suffixes and endings. Some examples, with Estonian and Finnish included for comparison: Consonants All Võro consonants (except and ) can be palatalized. The glottal stop (q, IPA ) is a very common sound in Võro. Grammar Nouns Endings are shown only in the back vowel harmony variant. The e of the illative ending does not undergo vowel harmony, so it never changes to õ. Only the more common endings are shown. There are some unusual/irregular endings that are only found in a few words or word types. Notes: The accusative is not usually considered a separate case in Võro grammars, as it is always identical to either the nominative or the genitive. When an ending beginning with d is attached to a stem ending in an obstruent,
