In the book Code Talker once he arrives at boarding school how does Ned Begay get his new name?

In the book "Code Talker," when Ned Begay arrives at the boarding school, he is given the name "Ned" by the school authorities as part of their effort to assimilate Native American students and erase their cultural identities. The school enforces English names and forbids the use of their native languages, so Ned adopts this new name to fit in. This experience highlights the broader theme of cultural loss and identity struggle faced by Indigenous peoples during this period.
