When I was first learning swedish I had a problem with possessives Han läser hans tidning,implies that he's not reading his own newspaper. He's reading someone else's Hon läser hennes bok ,also means she's reading someone else's book..she does not own the book You have to use sin for his/hers . Anderson gav min far en tidning ,han läser hans tidning . : it's andersons newspaper not your father's I hope that helped if there's anything unclear please let me know :)
