Besides the title, what are some symbols in Great Expectations?Great Expectations by Charles Dickens

In Great Expectations by Charles
Dickens, there are several
symbols:

• Satis
  House is, perhaps, the most salient of these symbols. 
  Satis, a Latin word, means satisfied; of course, the irony in this
  name is that Miss Havisham, the occupant of the house is anything but satisfied, nor is
  anyone else who comes there.


• The
  clocks arrested at twenty minutes to nine (8:40) are
  symbolic of Miss Havisham's spiritual death after having been jilted as she freezes time
  and refuses to change anything from that point.


• Miss
  Havisham's wedding dress and
  cake are symbolic of her physical decay and spiritual
  stagnation.


• Her wedding veil
  wraps around her like a shroud.


• The brewery
  in decay suggests the connection of commerce and wealth as well as the
  evils Dickens perceived in the Industrial
  Age.


• The crumbling stones and rusted
  gate of Satis House suggest the decadence of what Dickens considered a
  frivolous aristocracy.  That her relatives and the townspeople yet perceive the
  eccentric Miss Havisham as superior also indicates the reverence given to materialism
  which Dickens found offensive in his society.


• The
  mists on the marshes are symbolic of danger.  It is there
  that Pip first encounters the convict, and it is also on the marshes that Pip's life is
  threatened by Orlick at the sluice house.  Whenever Pip travels to and from London he
  must pass through the mists; this suggests that his development as a gentleman may have
  negative results.


• The prison
  ship represents what Robert Barnard in his essay "Imagery and Theme in Great
  Expectations" calls the transference of guilt from one character to another. 
  For instance, after his encounter with convict in Chapter One, Pip is ridden with guilt
  as he steals the food and file for Magwitch.  When he later returns to the marshes Pip
  is ridden with guilt for avoiding Joe on his visits and for his treatment of Biddy, as
  well as his feelings that "had some hand in the attack upon my
  sister."


• The names of
  characters are also symbolic: Estella, whose name means
  star, is an unobtainable as a star for Pip, but viewed by him as
  beautiful and desirous and one to be reached
  for. Pumblechook, who is pompous and fawning before the
  wealthy, symbolizes the rising middle class who wish to rise the higher social class. 
  When Pumblechook learns that Pip has acquired money, he congratulates him and treats him
  with a new respect.  Also, Bentley Drummle, a lout,
  represents the falsity of class distinctions as this coarse and crude man is allowed
  into what is seemingly polite society.  Magwitch's name
  suggests both his wicked past and his magical provision of Pip's "great expectations." 
  Pip's servant, whose name is Avenger suggests the
  pretensions of Pip in having a servant.  Avenger does not serve Pip at all; in fact, it
  is difficult for Pip to get him to do
  anything.


• Fire, which is
  often symbolic of cleansing, represents Miss Havisham's spiritual cleansing from her sin
  of vengeance against men as she is burnt after asking Pip his
  forgiveness.
