When can I get my broken car fixed?
If it makes you feel better, then I don't mind at all, Aya.
The farmer’s broken tractor was fixed.
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 version is similar to that, to be fixed. This word is for when something is fixed, but you're not the one fixing it.
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! You have to fix it now! (なお). This will also work with the similar word, 直す, which you'll learn soon if you haven't already.
