'bromoacetanilide' originates from 'English', specifically the word 'bromo-' meaning 'bromine' and 'acetanilide' meaning 'a derivative of aniline'.

'bromoacetanilide' changed from 'acetanilide' by the addition of a bromine atom, and eventually became the modern English word 'bromoacetanilide'.

Initially, it meant 'a derivative of acetanilide with bromine', and this meaning has largely remained the same in modern usage.
