Question: are onomatopoeias the same in all languages?
Answer: Onomatopoeic words aren't even the same in the same language. 'Woof,' 'bow wow', 'bark', 'yip' and 'ruff' are all English onomatopoeias for the sound a dog makes, and none of these are the same as 'wan wan', the sound a Japanese child would most likely ascribe to a dog.
