In the novel, a new name is connected with the notion of being “twice-born”. What does their first name signify and then what does their second name signify? ( question continued in details)

How do the changes connect to the characters and their stories in the novel?

What do you think is significant about who renames each character?

Could it be argued that their first name and their “re-born” name each represent different character archetypes?

ive looked every where online for help and i have found nothing
