Vowel Harmony

Basically, the vowels used in affixes are conditioned by the vowel(s) of the root word. The term is used most frequently of the Finno-Ugric languages and the Turkic langs (which is one reason some people lump the whole lot together in a larger Altaic group). E.g. in Turkish the plural ending is either -ler or -lar according to whether the root word contains front vowels or back vowels, respectively, thus:

adam (man) adamlar (men)
kulak (ear) kulaklar (ears)
ev (house) evler (houses)
erik (plum) erikler (plums)

In fact these languages also often include rounded and unrounded vowels in their schemes of vowel harmony. Unfortunately, this would mean giving examples with diacritics and/or symbols which tend to get corrupted by some mail-readers. But look for a book on Turkish, Finnish or Hungarian and you'll soon get the idea.

Another sort of vowel harmony is often encountered in African languages where all the vowels are either lax or tense.

In my proposed scheme the written, stressed vowels are:

  1. high front

    {i} = /i/
    {e} = /e/

  2. high back

    {u} = /u/
    {o} = /o/

  3. low center

    {a} = /a/
    {w} = /au/
    {y} = /ai/

The unwritten, unstressed vowels in affixes are:

/i/ if root vowel is high front
/u/ if root vowel is high back
/a/ if root vowel is low center
