'baryphonic' originates from Greek, specifically the elements 'barus' and 'phōnē', where 'barus' meant 'heavy' and 'phōnē' meant 'voice' or 'sound'.

'baryphonic' developed in modern English by combining the Greek combining form 'bary-' (from 'barus') with the suffix '-phonic' (from 'phōnē'), forming the adjective 'baryphonic'.

Initially, it meant 'heavy voice' in a literal sense, but over time it evolved into its current meaning of 'producing or having deep, low-pitched sound'.
