The Japanese language has a large inventory of sound symbolic or mimetic words, known in linguistics as ideophones. Such words are found in written as well as spoken Japanese. Known popularly as onomatopoeia, these words do not just imitate sounds but also cover a much wider range of meanings; indeed, many sound-symbolic words in Japanese are for things that make no noise originally, most clearly demonstrated by 'silently' (しーんと, shīnto).
