How morphological is Hungarian vowel harmony?

There is a significant degree of phonological indeterminacy in front/back harmony Hungarian (HVH), which manifests itself lexical variation and/or vacillation. Harmonic behaviour the zone strongly supports hypothesis that harmonic classes individual roots belong to are organized as paradigmatic system, very similar inflectional classes. Such lexically determined declension required independently vowel account for various other conditioned alternations Hungarian, e.g., involving linking vowels suffixes and yod 3rd person possessives. A further evidence morphologisation HVH paradigm uniformity effect, Uniformity, reduces uncertainty by making stem’s predictable from its root. Thus, morphology (paradigmatic uniformity) addition (and sometimes overriding) phonology.
