'amidoazobenzene' originates from 'German', specifically the word 'Amidoazobenzol', where 'amido-' refers to the presence of an amide group and 'azo-' refers to the nitrogen double bond characteristic of azo compounds.

'Amidoazobenzol' transformed into the English word 'amidoazobenzene' as the compound became more widely used in English-speaking countries.

Initially, it referred to a specific chemical structure, and this meaning has largely remained the same in modern usage.
