Accompanying symbols of (1) language symbols, such as sound level, size speed, font, size, thickness, neatness or scribbling, etc. Are companions of spoken language or writing, also known as paralanguage. Paralanguage not only plays an auxiliary role in language, but also has its own meaning.

(2) Non-verbal symbols are body symbols such as action, gesture, expression, sight and posture. Because they can also convey information like language, some people also call it "body language". Generally speaking, body symbols can be used alone or together with language, and they play an important role in forming context (communicative situation).

(3) Non-verbal symbols are materialized, active and stylized symbols with independence and initiative. Language is not the only inherited conceptual system. Various nonverbal symbol systems such as rituals and customs, badges and flags, clothing and food, music and dance, art and architecture, houses and courtyards, cities and consumption patterns are all included.

These symbol systems can be found in all fields of human life.
