IDEOPHONES WORLDWIDE
nIt has long been known that a feature characteristic of  languages worldwide, but particularly those of Africa, is ideophones, words of a distinct semantic type, which may fill one or many syntactic slots.
n Ideophones may be defined as a subset of sound symbolism, which also includes phonaesthemes and  other methods of indicating qualities (for example alternations of ± ATR vowels)
nThis field is often referred to as phonosematics and has a long history in Western philosophy. Plato’s Cratylus has a discussion of phonaesthemes, for example
nIdeophones (or ‘expressives’ in Asian terminology) have begun to be of more interest to the broader scholarly community (e.g. Hinton et al, 1994).
