## Emergence
**Emerges from:** [marks](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-marks.visual), [meaning](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-meaning.significance), [pattern](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-pattern.regularity), [mean](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-mean.signify), [show](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-show.visual), [visual](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-visual.perceptual)

**Through:** A visual mark with regular form interacts with perceptual and semantic faculties to signify meaning.

**Novel properties:**
- symbolic interpretation
- visual significance
- regular pattern recognition

## Examples
- The equal sign '=' in mathematics, standardized by Robert Recorde in 1557, replaced verbose phrasing with a consistent visual mark. *(mathematics)*
- The red octagonal 'STOP' sign, mandated by the 1922 Manual on Uniform Traffic Control Devices, standardized road safety across the U.S. *(engineering)*
- The swastika, used for millennia as a religious symbol, acquired new meaning through its regular use by Nazi Germany from 1930 onward. *(institutions)*
