When we analyze something we better understand and quickly memorize it. The same is with the learning Chinese characters. When we see and understand what radicals and components the character consists of, our mind does not resist to absorbing this information.
We easily learn what we clearly understand. If we do not understand the structure of a character, then we need to spend hours and days writing and writing this character.
Let us analyze the Chinese character 去 qù ‘go’
去 qù go
土 tǔ earth
十 shí ten
一 yī one
丨 gǔn line
一 yī one
厶 sī private
Now the character 去 looks more familiar to us, doesn’t it?
Synonyms: Structural analysis of the Chinese characters, Breakdown of the Chinese characters.
