Name.
The name ‘Deuteronomy’ is derived from the LXX where it is called deuteronomion, the ‘second law’. This goes back to a misinterpretation of 17:18 by the LXX translators, where the expression mišneh hattôrâ means a ‘copy of (this) law’. In the Jewish tradition, the name of the book is děḇārîm (words), which is a name taken from the opening verse of the book.
