So, it's Tuesday, and so that means time for Kanji.
If you are studying Japanese, you have probably seen 雷, which means lightning.
But, there are several different ways to say lightning.
The last one will blow Japanese people's minds away if you have write it for them. It was mainly used in like old shrines and temples, but you will never see it now.
The most famous usage of it I know about is in 水滸伝 (Suikoden... yeah, like the RPG) one of the chapters is titled 霹靂。
