What is the theme of the novel and is there a relation between the theme and the term rememory that Morrison uses in the novel?

Morrison presents several themes in the novel; slavery’s destruction of identity, the importance of community solidarity, and the powers and limits of language.

Rememory;

"Instead of using the words "remember" and "forget," Sethe uses the words "rememory" (both a noun and a verb here) and "disremember." To Sethe, the past is alive in the present, and thus the word "remember" is substituted with the more organic "rememory," reminding us that everything is held in memory. Similarly, the word "forget" lacks the conscious effort that the characters must employ to commit such an act. Thus, they "disremember" things, with the implication that they force them to the back of their minds." (1)
