'anglomaniac' originates from English, specifically from the combination of 'Anglo-' meaning 'English' and '-maniac' meaning 'one who has an excessive enthusiasm or obsession.'

'anglomaniac' was formed in the 19th century from 'anglomania' (excessive admiration for England) and the suffix '-ac' (denoting a person with a mania), and eventually became the modern English word 'anglomaniac.'

Initially, it meant 'a person obsessed with England or English things,' and this meaning has largely remained the same in modern usage.
