What are some examples of diction, imagery, and symbolism in the book "Night," by Elie Wiesel?
An example of symbolism is the cattle car.
I'm sorry I don't have any answers for diction and imagery (I don't own a copy of night so I'm going off of memory).
Partway through the book, our narrator Wiesel and his family are herded into a cattle car bound for Auschwitz.
The cattle car itself is an example of symbolic setting, as the cattle car represents these things: it furthers the conflict Wiesel will face when he comes to terms with his lack of control over the situation (being unable to move literally and being unable to escape from the camp) and sets an ominous and threatening tone for the reader (foreshadowing; the darkness of the cattle car with the smoke of Auschwitz, etc).
