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.

Fungwa 通过在名词词根的非高元音前面标记小词，并通过支持名词词根的非高元音来标记增强词。根元音突变被认为是具有 [―back] 和 [+back] 特征作为其语音指数的缩小和增强语素的影响。语素的形义关联与各种语言中音高符号的模式是一致的。因此，Fungwa 为声音大小的象征主义提供了明确的和确定的证据。为了解释特征词缀的实现，我假设特征对应约束。鉴于特征词缀不是在高元音上实现的，我认为特征词缀的实现涉及基于突出的许可条件。
