I guess this entry needs a revision.

If you want to say "I am sorry" to apologize for something you have done wrong, you would say Ngiyaxolisa! or Uxolo!.

If you want to say "I am sorry" to express sympathy for something that happened to somebody else you would say Phephisa! to one person or Phephisani! to more than one person.

"Excuse me, ..." is Uxolo, ...

Chaka Khan's "I feel for you" would be Ngiyakuzwela.
