semiotics

In philosophy and linguistics, semiotics is the branch of study concerned with the meanings and functions of signs and symbols.

Have you ever thought about traffic lights? How did we decide red means "stop," green means "go," and yellow means "slow down" (even if most people speed up)? Traffic lights are symbolic, and the study of symbols is semiotics. Just don't get absorbed with semiotics when there are cars behind you at a traffic light!
