Northeastwards → It is formed from "north" (from Old English *norð*, meaning the direction toward the North Pole) and "east" (from Old English *ēast*, meaning the direction toward the rising sun), combined with "-wards" (meaning in the direction of). The word "northeastwards" means in the direction toward the northeast.
Think of heading toward the 'north' and 'east' — that's why 'northeastwards' means moving in that direction.
