Difference between Sign and symbol

Sign

A sign is that which takes the place of another thing and object, that is, it represents a certain reality or concept for those who interpret it. Signs are those signals whose purpose is to communicate something that can be perceived by humans and other living beings if necessary.

Human beings receive information from verbal and non-verbal statements from our peers and from nature, so it can be said that we live in a world of signs that transmit information to us.

Symbol

It is the perceptible representation of an idea that is associated with it by a social convention. It has a conventional link between its meaning and what it denotes. A symbol serves to represent an idea that is perceived through the senses. It allows us to externalize or reflect a thought or concept through a social convention, that is, it is arbitrary. A symbol is that which represents and embodies certain values.
An example of this is the national symbols that make up the banner of a country or the religious symbols used to represent and symbolize deities or religious stories. For linguistics, symbols are scientific or technical abbreviations that use signs outside the alphabet or present in it and that, unlike traditional abbreviations, are not accompanied by a period.
