Phonestheme
A phonestheme (, foh-NESS-theem; phonaestheme in British English) is a pattern of sounds systematically paired with a certain meaning in a language. The concept was proposed in 1930 by British linguist J. R. Firth, who coined the term from the Greek φωνή phone, "sound", and αἴσθημα aisthema, "perception" (from αίσθάνομαι aisthanomai, "I perceive").
