Phonotactics
Syllable structure
The common syllable structure in Ravna is CV(C).
The final consonants cannot be glottal.
Other constraints
The vowel /ɨ/ can only occur where the syllable constraint forbid it to disappears. For example, Ravna is actually Ravina, but since i is unstressed, it disappears.
Final consonants are devoiced, unless there is no voiceless equivalent for the consonant. Ravna is pronounced [ˈraːfna] but Ravino is /raˈviːno/.
Glottal stop /ʔ/ also disappears when a compound/suffixed word forms with two same vowels colliding, or when a consonant is followed by a vowel.
Example:
ravi (root) /ˈraːvɨ/ + ino /ʔino/ (human, person, people) → Ravino /raˈviːno/
(not *Ravi'ino /ˈraːvɨʔino/)
