A symbol is a mark, sign, or word that indicates, signifies, or is understood as representing an idea, object, or relationship. Symbols allow people to go beyond what is known or seen by creating linkages between otherwise very different concepts and experiences. All communication (and data processing) is achieved through the use of symbols.

A symbol is a drawing, shape, or object that represents an idea, object, or amount of something. The most common symbols are letters, which are symbols of words and sounds. A symbol can be an actual object (such as the cross, a symbol of Christianity or a scepter, a symbol of royalty and power), or a certain color or pattern.

A symbol is an object, action, or idea that stands for something other than itself, often of a more abstract nature. Symbolism creates quality aspects that make literature like poetry and novels more meaningful.
