Chuvash

To keep in mind

• A symbol that forces enforces a certain vowel harmony. Perhaps some kind of 'harmony' boundary which is separate from 'morpheme boundary'. Consider the following cases:
  • Acronyms, which harmonise as if they were spoken out.
  • Foreign words, which harmonise by default in a particular way regardless of stem vowels.
  • Words which change harmony half way through, or have elided vowels/morphemes which change harmony but can't be seen on the surface.
