reading a wikipedia article about fr. ronald knox. i take it the fr. means "friar" but maybe i am wrong.
The french version of the article says mr. knox's title became "Mgr Knox" once he had become a priest. what exactly does "mgr" stand for? (in the article the typeset is different but copy and paste did not do the trick here: the m is normal size, the gr small and "to the top"...)
sorry my dictionary did not help here
