'amidoazobenzol' originates from German, specifically the word 'Amidoazobenzol', where 'amido-' refers to the presence of an amine group and 'azo-' indicates the presence of a nitrogen double bond.

'Amidoazobenzol' was directly borrowed from German into English, retaining its chemical nomenclature.

Initially, it meant 'a compound with amine and azo groups', and this meaning has largely remained the same in modern usage.
