The form and meaning of symbols are general. Through the recognition and understanding of * * *, people can use and understand symbols in various fields, thus achieving effective communication and exchange.

First, the form of symbols refers to its external manifestations, usually expressed by specific symbols, letters, numbers, etc. These forms are given meaning in a conventional way, so they are universal and can be widely accepted and understood through the understanding and application of * * *.

Second, the meaning of a symbol refers to the concept, information or meaning it represents. The symbol itself has no fixed meaning, but is endowed by people's understanding and agreement. These meanings are usually based on the same understanding of a certain rule system or cultural background, so they are also general.

For example, the letter "a" stands for phoneme/? /,which stands for an element in an integer set in mathematics, is widely accepted and recognized.

Third, the generality of symbols enables people to communicate and communicate. No matter in language, mathematics, music or other fields, they all rely on the form and meaning of symbols to convey information and express ideas. The universality of symbols also endows them with certain universality and applicability, which makes them widely used and understood.

Hierarchical system of language symbols

This system can be understood from two aspects: one is the law of composition, and the other is the law of operation.

1, the law of language system is mainly manifested in the hierarchy of structure, that is to say, language is a hierarchical device, which can be divided into several levels from low to high, or from bottom to top, so that the symbols composed of sound and meaning are "in their proper places".

2. Language symbols are the combination of sound and meaning, so sound and meaning are naturally at the bottom. "Sound" is a chaotic and fuzzy linear sound stream. Just like laughing and crying, tiger howling and wolf howling, the structural components of sound are inseparable. The same is true of "righteousness", which is chaotic and vague and can't distinguish the boundaries of meaning.
