To Happen, To Take Place
intransitive verb, godan verb
You know that 起きる means "to wake up", but did you learn its secondary meaning, "to occur"? Well, this word means only to occur. Just imagine an incident occurring involving a uranium core (こる) to remember that this means to occur. After all, uranium core incidents don't wake up, do they?
The reading is the same as what you learned with the kanji and the same as 起きる too, meaning you should be able to put together the reading on your own.
I never expected something like this would happen.
Please calm down and think carefully about what's taken place.
"Hey, do you want to kiss me?" "Absolutely no way would I ever want to kiss you in a million years. That would never happen even if heaven and earth were turned upside down."
