I agree that in Polish the term is used in reference to Englsh speaking countries; however, not always (the historical meaning of it apart).
There is one wording that comes to mind and is a point in case here: kraje anglosaskie. It is used often enough in media that it should be known by the average Polish. Hearing it, I mainly think of three counries: the UK, the US and Australia. If I think more New Zeland comes to mind and vacilate about Canada.This may well be a personal thing, though.
When I hear "Anglosas", the first thing I think of are the English, however. And I can't quite wrap my head around a wider scope of this term, but then again it might be a personal matter.
Please correct my errors! Thanks.
Corrigez-moi, s'il vous plaît! Merci.
