Sign systems are ways in which we communicate meaning through symbols, gestures, or sounds. These systems can be found in languages, art, and even traffic signs. For example, the English language uses words as symbols to convey ideas, while traffic signs use images and colors to guide drivers safely. In addition to language, sign systems also include non-verbal communication, such as body language and facial expressions. These signs can express emotions and intentions without using words. Understanding these systems helps us interpret messages more accurately, whether in everyday conversations or in cultural contexts.
