Hi, I’m still a complete beginner going through Season 2 of TextFugu.
I was confused by the readings of the numbers kanji. TextFugu states that:
Note that most vocab words, when all alone (with no other kanji attached to them) use the kun’yomi readings. Numbers are not like that. They use the on’yomi reading when left alone like this. Just remember that numbers are the exception to the rule.
It also gives the on’yomi reading for 十 as じゅう, and the on’yomi reading for 七 as しち.
However, one of the practice pages has the sentence: 十は七じゃありません, which is read as じゅう は なな じゃありません. So the kun’yomi reading for 七 (なな) is used.
Why is that? Is 七 an exception to the rule, or is the rule incorrect? Or am I missing something?
Thank you very much for any help!
