Semantic entry: 82.2

Semantic domains: Spacial Orientations

Subdomains: North, South, East, West

Notes: In most languages east and west are related to the rising or setting sun, although in some languages there may be some local geographical feature which serves as a marker of direction, for example, the location of a particular mountain, the ocean, or a river. For north, some languages employ ‘to the left of the rising sun,’ that is to say, the direction is oriented in terms of the left hand of a person facing toward the rising sun. Similarly, south would be ‘to the right of the rising sun.’
