[chryuop]

When I started studying by heart the kanji (reading and meaning) I had found on the book I used that with ON reading you can have other kanji, while with KUN readings you will have hiragana.
Basically I knew that for roots of verbs you use the KUN reading and not the ON reading.

While making flashcards I encountered few exceptions and they all used the same hiragana. I don't remember all of them, but the ones I remember are: 点じる、転じる、生じる. What is that じる and does it have a special use with ON reading of kanji?
