Life
independent noun
A vocab made from a single kanji all alone usually keeps at least one of the meanings of its kanji parent. In this case, that's life.
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:
The Book of Enoch (いのち) has passed down your fate and told you how to use your life. You must read the book of Enoch and find out what you're supposed to do.
コウイチはわたしたちみんなの命のおん人です。
We all owe our lives to Koichi.
おねがいですから、ワニカニでかん字をべん強することよりもご自分の命を大切にしてください。
Please, please value your life more than learning kanji on WaniKani.
セーラームーンの命が危ない！
