First, the method of distinction.
1, according to the sememe (radical): If words are composed of the same sememe, then these words can be classified into one category. For example, the words next to the word "wood", such as "forest", "forest" and "peach", are all words related to trees or wood.
2. According to phonetic notation (phonetic notation side): If words are composed of the same phonetic notation, they can be regarded as one class even if their meanings are different. For example, "Qing", "Qing" and "Qing" all contain a homonym "Qing", which means similar pronunciation.
3. According to structure: Words can be classified according to their structures, such as left and right structures, up and down structures, internal and external structures, etc.
4. According to the meaning: classify words according to their meanings in words. For example, some words have specific meanings in different idioms or phrases.
5. According to the purpose: In some cases, words may be combined because of their use in specific fields or occasions. For example, common words in calligraphy and professional words in medical terms.
6. Pronunciation: Although some words have different shapes, they are pronounced the same in some dialects or accents, and such words can also be regarded as similar words. In specific operations, one or more methods can be selected for classification according to the above principles. For example, you can first group Chinese characters according to semantic symbols, and then subdivide them according to structure or comments within each group.
Second, expand knowledge.
The origin of similar characters can be traced back to the formation and development of Chinese characters. Chinese characters are hieroglyphics, and their emergence and evolution have gone through different stages, such as Oracle Bone Inscriptions, bronze inscriptions, seal script, official script and regular script.
2. hieroglyphics: The original Chinese characters expressed meaning by depicting images of things, which were gradually simplified and abstracted, forming early graphic symbols.
3. Pointers and cognitive words: With the development of society, people need to express more concepts, so there are pointers that express abstract concepts with simple lines or symbols and cognitive words that are combined by two or more parts to form new meanings.
4. Pictophonetic characters: Pictophonetic characters are the main components of Chinese characters, consisting of a semantic symbol (also called radical) and a note (also called sound). This structure enables Chinese characters to express meaning and prompt pronunciation, which greatly increases the number and expressive ability of Chinese characters.
