Some words and phrases, claims the theory, actually ‘sound like’ that which they mean: such a form is ‘onomatopoetic’. [...]. The fact that each form consists of two syllables, with a high front vowel in the first and a low vowel in the second, an initial voiced stop and a final nasal in each syllable, is indicative of the onomatopoetic.
