In linguistics, sound symbolism is the perceptual similarity between speech sounds and concept meanings. It is a form of linguistic iconicity. For example, the English word ding may sound similar to the actual sound of a bell.
Linguistic sound may be perceived as similar to not only sounds, but also to other sensory properties, such as size, vision, touch, or smell, or abstract domains, such as emotion or value judgment. Such correspondence between linguistic sound and meaning may significantly affect the form of spoken languages.
