I don't feel any difference.Here are three examples with "marry" from the Cambridge Online Dictionary:
1) Men tend to marry later than women.
2) They don't have any plans to marry at present.
3) He never married.
Will there be any change of meaning if "marry" is substituted with "get married" in the above sentences (in the proper form)?
Which of the two (marry / get married) would be more natural? more formal? (I am not sure, but I think I read somewhere that "marry" sounds more formal than "get married" )
P.S. I am only interested in the examples without an object, not "
to marry somebody".
