Marley

• 'I wear the chain I forged in life'-just like how the 'chain' is made of links, which are all interconnecting, this parallels with the idea how Marley is warning Scrooge that his obsession with money and his lack of compassion for others, is directly connected to his affliction.
• 'dragging a heavy chain'-the chain is an extended metaphor for the restricting and eternal consequences of being parsimonious. The use of the tedious verb 'dragging' provoke a sense that the eternal punishments that he is suffering with have been going on for a long period of time
