'amphoricity' originates from the Greek word 'amphora,' where 'amphi-' meant 'both' and '-phoros' meant 'bearing.'

'amphora' transformed into the medical term 'amphoric' in English, eventually leading to the noun form 'amphoricity.'

Initially, it referred to a type of sound resembling that produced by blowing across the mouth of an amphora, but over time it evolved into its current medical usage.
