To Be Fixed
intransitive verb, godan verb
This word consists of kanji with hiragana attached. Because the hiragana ends with an う sound, you know this word is a verb. The kanji itself means fix, so the verb 直る is similar to that: to be fixed.
直る is intransitive, so it doesn't take a direct object. In other words: don't use it to say "I fixed it," but do use it to say "It's fixed!" Imagine a British person excitedly shouting, "My loo (る) was broken, but now it's fixed!"
Since this word consists of a kanji with hiragana attached, you can bet that it will use the kun'yomi reading. You didn't learn that reading with this kanji, so here's a mnemonic to help you:
You have to learn the なお part. Think of it this way. Something needs to be fixed. It's urgent! It has to be fixed now! (なお).
