What does the prefix 'Anglo' refer to?

Answer 1

The term Anglo is used as a prefix to indicate a relation to the Angles, England or the English people, as in the phrases 'Anglo-Saxon', 'Anglo-American', 'Anglo-Celtic', and 'Anglo-Indian'. It is often used alone, somewhat loosely, to refer to a person or people of English ethnicity in the The Americas, Australia and Southern Africa. It is also used, both in English-speaking and non-English-speaking countries, to refer to Anglophone people of other European origins.

Anglo is a Late Latin prefix used to denote "English-" in conjunction with another toponym or demonym. The word is derived from Anglia, the Latin name for England, and still the modern name of its eastern region. Anglia and England both mean "Land of the Angles", a Germanic people originating in the north German peninsula of Angeln.

Anglo is not a technical term.[citation needed] There are linguistic problems with using the word as an adjective or noun on its own. For example, the 'o' in Anglo means 'and' (Anglo-Saxon means of Angle and Saxon origin), so there is only an apparent parallelism between, for example, "Latino" and "Anglo". However, a semantic change has taken place in many English-speaking regions, so that in informal usage the meanings listed below are valid.
