However,,, and in a non-initial syllable are neutral vowels . / o? /, and / e? / never appear in any but the first syllable of a word.

However if only neutral vowels appear in a stem, the stem is treated as though it is of front vowel assonance and all suffixes must contain front vowels.
23.
Any vowel would have done the job, but a neutral vowel is the usual choice : Proto-Indo-Iranian * " zhrd-Y " from which, by regular sound laws, " hrdi ".
24.
Where a foreign word violates vowel harmony by not using front vowels because it begins with a neutral vowel, then last syllable generally counts, although this rule is irregularly followed.
25.
As shown in the examples, neutral vowels make the system unsymmetrical, as they are front vowels phonologically, but leave the front / back control to any grammatical front or back vowels.
26.
In the science of language that calls itself linguistics, a schwa is a neutral vowel sound, its symbol an inverted e, pronounced uh and usually unstressed, as the a in ago or the i in easily.
27.
Usually the mouth is relaxed and a fairly neutral vowel is produced, and since the sound is shorter and quieter the effect isn't that noticeable ( unless you're actually listening for it ) .-Rainwarrior 15 : 43, 5 October 2006 ( UTC)

Another feature attested in the Finno-Ugric vocabulary is that " * i " now behaves as a neutral vowel with respect to front-back vowel harmony, and thus there are roots such as " * niwa-" " to remove the hair from hides ".
29.
Although a schwa-like quality [ Y : ], appears to be the most commonly used, some speakers consistently using the neutral vowel [ h : ] instead, and others use both vowels in the same sentence, depending on the quality of the previous word last vowel.
30.
Finally, languages that do have vowel harmony often allow for lexical " disharmony ", or words with mixed sets of vowels even when an opaque neutral vowel is not involved . point to two such situations : polysyllabic trigger morphemes may contain non-neutral vowels from opposite harmonic sets and certain target morphemes simply fail to harmonize.
