## Emergence
**Emerges from:** [direction](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-direction.spatial), [west](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-west.direction), [difference](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-difference.relation)

**Through:** when a direction is different from west and that direction is east

**Novel properties:**
- opposite orientation
- unique directional label

## Examples
- At noon in Cairo, the sun rises in the east, casting a shadow toward the west along the Nile. *(geography)*
