'anti-Anglo' originates from the Greek prefix 'anti-' meaning 'against' combined with 'Anglo' (from the name of the Angles/English).

'anti-' comes from Greek 'anti' meaning 'against'; 'Anglo' is a modern shortening referring to the Angles/English, ultimately from Latin 'Angli(i)' (the name of the Germanic tribe) and Old English 'Englisc'. The compound 'anti-Anglo' formed in modern English by prefixing 'anti-' to 'Anglo'.

Initially, 'anti-' meant simply 'against' and 'Anglo' referred to the Angles or English; combined, the term has come to mean opposition to English/British people, culture, or influence in political or cultural contexts.
