nAn aspect of ideophones in most African languages is reduplication; words are wholly or partly reduplicated according to language-internal rules and it is often these reduplications that give the onomatopoeic sense that plays some role in their generation.
nIdeophones tend to be polysyllabic and
in some cases can be freely extended.

relationship between canonical
structures of words in a language and the form of ideophones
