Featural affixation and sound symbolism in Fungwa

Fungwa marks the diminutive by fronting non-high vowels of nominal roots and the augmentative by backing non-high vowels of nominal roots. The root-vowel mutation is considered to be an effect of diminutive and augmentative morphemes which have [―back] and [+back] features as their phonetic exponents. The form–meaning association of the morphemes is consistent with the pattern of sound-size symbolism in various languages. Thus Fungwa presents categorical and deterministic evidence for sound-size symbolism. To account for the realisation of the featural affixes, I assume featural correspondence constraints. Given that the featural affixes are not realised on high vowels, I argue that the realisation of the featural affixes involves a prominence-based licensing condition.
