To Be Damaged
To Go Bad, To Spoil
intransitive verb, godan verb
The kanji means wound, and this verb is intransitive, so it means to be damaged or to go bad. After all, fruit with a wound on it is going bad, isn't it?
This shares the same reading as 痛む. The meanings are similar too, so that should be easy to remember, unless your brain was damaged by these mnemonics or something.
