Intercardinal directions

The intercardinal (intermediate, or, historically, ordinal) directions are the four intermediate compass directions located halfway between each pair of cardinal directions. * Northeast (NE), 45°, halfway between north and east, is the opposite of southwest. * Southeast (SE), 135°, halfway between south and east, is the opposite of northwest. * Southwest (SW), 225°, halfway between south and west, is the opposite of northeast. * Northwest (NW), 315°, halfway between north and west, is the opposite of southeast. These eight directional names have been further compounded known as tertiary intercardinal directions, resulting in a total of 32 named points evenly spaced around the compass: north (N), north by east (NbE), north-northeast (NNE), northeast by north (NEbN), northeast (NE), northeast by east (NEbE), east-northeast (ENE), east by north (EbN), east (E), etc.

, adding ''laut'' (sea) to either east (''timur'') or west (''barat'') results in northeast or northwest, respectively, whereas adding ''daya'' to west (giving ''barat daya'') results in southwest. Southeast has a special word: ''tenggara''. Sanskrit and other Indian languages that borrow from it use the names of the gods associated with each direction: east (Indra), southeast (Agni), south (Yama/Dharma), southwest (Nirrti), west (Varuna), northwest (Vayu), north (Kubera/Heaven) and northeast (Ishana/Shiva). North is associated with the Himalayas and heaven while the south is associated with the underworld or land of the fathers (Pitr loka). The directions are named by adding "disha" to the names of each god or entity: e.g. Indradisha (direction of Indra) or Pitrdisha (direction of the forefathers i.e. south).
