A sign is any written or drawn representation that expresses or indicates the existence or meaning of that particular thought. On the other hand, a symbol is a representation of an abstracted idea with a sign, shape, colour etc. because of convention, association or resemblance. Signs and symbols are synonymous terms that express the same meaning. Symbolism is the ideas behind the symbols used for the production of the work. They are the suggestions through imagery of something that is invisible or intangible. This representation of the material object is not simply for its own interest or beauty, but as standing for an abstract idea.
Symbols embody the ideas, norms, values and beliefs of a group, association, ethnic society or nation. Therefore, when they are used in the production of artefacts the sole aim is using it to propagate and educate the users about the cultural gems of their society. This makes artefacts produced with these symbols functional.
