Cardinal direction
Four main compass points used for navigation and orientation.
Cardinal directions are the four main compass directions: north, east, south, and west. Intercardinal directions (northeast, southeast, southwest, northwest) and secondary intercardinal directions further divide the compass into 16 and 32 named points.

Lore & Background
The intercardinal directions—northeast, southeast, southwest, northwest—lie halfway between each pair of cardinal directions. Secondary intercardinal directions, such as north-northeast and west-southwest, further subdivide the compass into 16 named points, and tertiary intercardinal directions yield 32 named points.
Reader's Guide
Cardinal directions are fundamental to navigation, used in compasses, GPS receivers, and trigonometry. They are also applied beyond geography, including vertical positioning (elevation, depth) and three-dimensional Cartesian coordinates. In astronomy, cardinal points on celestial bodies are defined relative to the celestial poles. Culturally, many traditions associate colors with cardinal directions—for example, east with green/blue, south with red, west with white, north with black, and center with yellow in Chinese and other Asian systems. The Germanic names for cardinal directions replaced Latin terms during the Migration Period, with etymological roots in Proto-Indo-European words for 'submerged,' 'dawn,' 'seethe,' and 'evening.'
Did You Know?
- Secondary intercardinal directions include West-northwest (WNW) and East-southeast (ESE).
- In astronomy, the North point on a celestial body is the limb point closest to the North celestial pole.
- The Germanic name 'north' derives from Proto-Indo-European *nórto-s meaning 'submerged.'
Frequently Asked Questions
What are the Cardinal directions in Lines & Hemispheres 1-24?
They are the four primary compass points—North, East, South, and West—that serve as the foundational reference for all navigation and orientation. Everything else on a compass rose is measured relative to these four anchors.
How do Cardinal directions relate to the intercardinal and secondary intercardinal points?
The four intercardinals (Northeast, Southeast, Southwest, Northwest) fall exactly halfway between adjacent cardinals, and the eight secondary intercardinals (such as WNW, NNE, ESE) subdivide those gaps further. Together they expand the compass from 4 named points to 16 and then 32.
Why are the Cardinal directions considered the most important compass points?
They form the baseline grid for bearing, heading, and map orientation, so every other named direction is defined as a fraction of the distance between two cardinals. Without them, the entire 32-point compass system loses its structural reference.
How many total named compass points exist when all subdivisions are counted?
Starting with the 4 cardinals, adding the 4 intercardinals gives 8, and inserting the 8 secondary intercardinals brings the total to 16 named points in the standard system (with further subdivision reaching 32). The cardinals remain the four anchor points around which all others are organized.
