Hello! I’m finishing up season 2 of textfugu right now, but I’m a little confused about one of the sentences on the practice page. It seems like there have a been a few questions recently about pronunciation of kanji, and I’m sure a lot of the concepts clear up over time. However, I figured it couldn’t hurt to ask. So the sentence is: 十は七じゃありません. On the kanji page for 十, it explains that for numbers, the on’yomi reading is often used if it’s just the kanji by itself. But when I listen to the pronunciation of this sentence, 七 is pronounced ‘nana’ which is the kun’yomi pronunciation. Is this just an exception, or am I not understanding something? Thanks in advance for your help!
