Translators: This phrase is spoken to inform the user that what is about to
be spoken is a cube root. For instance, for the cube root of 9 Orca would
say "cube root of 9, root end" (assuming the user settings indicate that root
endings should  be spoken). Note that the radicand, which follows the "of",
is unknown and might not even be a simple string; it might be the cube root
of another expression such as a fraction.
