Reason
Circumstance, Cause
noun
The kanji and the word are exactly the same. That means they share meanings as well.
Since this word is made up of a single kanji, it probably uses the kun'yomi reading. You did not learn this reading, so here's a mnemonic to help you:
When thinking about the circumstance of your current situation and the reason you're there (which is studying kanji and vocab). Whose fault is it? It's WaniKani's fault! But, your brain has been beaten to a mush from all the studying, so when you say "it's your fault" it comes out as "it's yue fault!" Go ahead and say it out loud that way.
