Language is the combination of the image of things in the mind and the sound made by people when they speak. It’s the concept and sound image. According to Saussure, the two elements are intimately united, and each recalls the other. Language is the way of communication passed down from generation to generation by human beings. It is the product of historical forces. Different languages are also symbols of different nations and cultures. It is the bridge between people and the cornerstone of the development of human society.

In modern graphic design, in addition to traditional language, symbols also bring convenience to people’s lives. Because the symbols themselves have specific meanings and cultural connotations, the symbols after being matched and recreated by designers then have formed a brand-new form of visual language – symbol language. Different from language, symbols are a single element, and the formation of symbolic language is that designers combine the symbols of different elements to obtain another meaning that they want to express. For example, road signs, warning signs, bathroom sign etc. Symbolic language has long been seen everywhere in our daily life.

Both traditional language and symbolic language play a very important auxiliary role in the design. For designers, language elements are like brushes in the hands of painters, and they are the best creative tools. Designers use different language elements and combine them with other elements to transform into a more diverse work. To transmit information in people’s lives, thereby promoting social development.
