“…To the extent that cumulativity is a general property of phonological patterns (McPherson & Hayes 2016, Zuraw & Hayes 2017, Breiss 2020, Hayes 2020), and if sound-symbolic effects show similar cumulative properties, then we may conclude that there exists a non-trivial parallel between phonological patterns and sound-symbolic patterns (Kawahara 2020a). This parallel would lend some credibility to the hypothesis that sound symbolism is a part of ‘core’ linguistic knowledge, as has recently been argued (Alderete & Kochetov 2017, Kumagai 2019, Jang 2020, Kawahara 2020a, b, Shih 2020). This is a rather radical conclusion, given the fact that sound symbolism has long been considered as being outside the purview of theoretical linguistics.…”
