sonorous

the word 'sonorous' has a direct lineage from latin, entering english in the early 17th century. it is built upon the latin root 'sonor-', meaning 'sound', which itself derives from the proto-indo-european root swen-, meaning 'to sound' or 'to resound'. the suffix '-ous', also of latin origin, imparts the meaning 'full of' or 'characterized by'. therefore, the literal construction 'full of sound' elegantly evolved into its modern meanings, describing either a physically deep and resonant sound or language that is impressively resonant and grand in style.

Structure: sonor (sound) + ous (adjective suffix) sonor (from latin 'sonor', meaning 'sound' or 'noise', from the verb 'sonare', 'to sound'); ous (a suffix forming adjectives, from latin '-osus', meaning 'full of' or 'characterized by').
