deep-voiced

The compound adjective 'deep-voiced' is a straightforward combination of two English elements. The first, 'deep', originates from the Proto-Germanic 'deupaz', carrying the core sense of profound depth, which was extended metaphorically to describe low-pitched sounds. The second element, 'voiced', derives from the noun 'voice', tracing back to Latin 'vōx, vōcis' (voice, sound). The compound logically follows the pattern of adjective-noun+ed, literally meaning "having a voice that is deep," directly linking the physical concept of depth to the auditory quality of low frequency or resonance in speech or song.

Structure: deep (having great depth) + voiced (provided with a voice) 'deep' is from Old English 'dēop', meaning having great extension downward or inward. 'voiced' is the past participle of the verb 'voice', from Old French 'voiz' (voice), ultimately from Latin 'vox'.
