Ring, Wheel, Loop, Circle
noun
The kanji and the word are exactly the same. That means they share meanings as well.
わ
Since this word is made up of a single kanji, it should use the kun'yomi reading. When learning the kanji, you didn't learn that reading, so here's a mnemonic to help you with this word: You put on the ring you found, hoping it will be the one ring to rule them all (invisibility!). Instead, it turns out it's a special Walken(わ) ring, made out of Christopher Walken's bones. It talks up to you, telling you how he kept this ring in his (*ahem*) butt during the war so he could get it to you. First of all, why is this ring talking? Second, why is it talking like Walken. Third, eww, gross, it was in his anus.
早くこの輪投げの輪を投げてくださいよ！
