What is anglicanization?

I think you mean 'anglicization'. It can refer to the conversion of a word originally part of another language into an English term, or sometimes the conversion of non-UK English idioms or spellings into UK English.

An example of the former is the word 'pork', which derives from the French 'porc', meaning pig. 'Porc' was anglicized to 'pork', meaning the flesh of a pig.


An example of the latter is the need to convert from US to UK English, e.g. 'color' to 'colour', 'pants' to 'trousers', 'sidewalk' to 'pavement' etc.
