what is a generic word? When the ancients made words, they made a word to express a meaning, but which word should be used to express a certain meaning? Sometimes there are certain rules; However, some words are still in the process of formation, and there is no certain rule. It is possible to use this word to express a certain meaning, or it is possible to use a homonym to express that meaning. This homonym is called a "generic word", and the word replaced by a generic word is called a "native word". For example, "I'm sorry, you don't appreciate it" (Yu Gong). At that time, wisdom was usually expressed by "Hui", but sometimes it could be expressed by "Hui", so "Hui" became a generic word of "Hui". Another example is "the Gods of Thunder and Lightning, the hills are crumbling." According to the general situation, it should be written as "crack", but in ancient times, "column" could also be used instead of "crack". So "column" became a generic word of the word "crack". This method has been preserved, so that Dr. Sun Yat-sen in the 2th century also wrote it according to this method. For example, "To the Three People's Principles and the Five Powers Constitution, which was sung 3 years ago, which was fought for by all the martyrs at the expense of their lives, will remain the same if it is not implemented (Huanghuagang)" Singing "is a generic word for" advocating ".
Another reason why the ancients used interchangeable characters is that the original characters can represent many meanings. Later, in order to reduce the burden of this word, a new word was created, but the old word was still in the ancient book. In the eyes of later people, the old word is a generic word, and the new word is the original word. For example, "printed books on the board have not been popular in the Tang Dynasty." The version used the board at that time. "Board" can mean wood board or printing plate. Later, in order to reduce the burden of "plate", a word "plate" was specially created to represent the printing plate, so "plate" became the generic word of "plate" and "plate" was the word.
In most cases, the pronunciation of the interchangeable word is the same as that of this word, because the interchangeable word is the homonym of this word. However, due to great changes in pronunciation from ancient times to the present, the pronunciation of some interchangeable words is inconsistent with that of this word. For example, "A boy's teacher, who teaches books and learns his sentences, is not what I call a person who tells his story to solve his confusion (Teacher Shuo)", and the interchangeable word "read" replaces the word "tease". The sound of "reading" is dú, and the sound of "teasing" is dò u.
