There are two ways to read kanji, On-yomi and Kun-yomi, and the differences are as follows.
音読み On – yomi
It is a reading based on the old Chinese pronunciation, and many of the meanings are not clear just by hearing them.
訓読み Kun – yomi
It is a Japanese reading of the meaning of a kanji, and many of the meanings can be understood just by hearing it. There are also kanji that require a sendigana, such as “represent” or “show”.
Some kanji even have special readings. For example, one is one person. We completely ignored the on’yomi and kun’yomi readings.
