Question

what does it mean by social marginalisation​

Answer 1

It means thinking someone as different from others and so keep them in a margin or limit.

For eg. One of your colleagues likes to play hockey while others like badminton, then one would rarely play with the colleague who likes hockey and so he or she is in a sense stopped to play hockey.

Marginalisation means giving a limit time some one or thinking them as different.

You also make margin on your copies to separate the written part from the numbered part. Therefore you are marginalising the numbered part that it cannot come to the written part.

Henceforth I believe that you must have been clear about social marginalisation from the above example.
