What direction is between south and west on a compass?

The direction that lies between south and west on a compass is southwest. In compass navigation, the cardinal directions are usually divided into four primary directions: north, east, south, and west. Each of these directions can further be subdivided into intermediate directions, which include northeast (between north and east), southeast (between south and east), southwest (between south and west), and northwest (between west and north).

Thus, southwest specifically indicates a direction that is 45 degrees to the southwest of due south and 45 degrees to the northwest of due west. This makes it the correct answer when identifying the position between south and west on a compass.
