I tried searching the forums, but couldn’t get a combination of words to see if someone has asked this or if there was an announcement or explanation.
In Level 10, there are several radicals that are the exact kanji I learned in previous levels: sell and fault come to mind, but maybe there were others.
Is this due to some reordering that happened, or is this intentional? Maybe this happened in earlier levels and I just was too inexperienced to notice.
All kanji are made up of radicals in this system. So if you have a new kanji that uses the same parts as 売, like 続, instead of just continually making bigger and bigger mnemonics, you convert the kanji you learned in pieces to a single radical, and that way the mnemonics stay relatively short.
Wow. This is so obvious when you say it. I’m not sure why it didn’t occur to me.
It’s still a little weird to formally make you go through a radical like that. If the mnemonics just used “sell” as if I understood that was a radical, I probably wouldn’t ever have realized it wasn’t formally a radical learned during that section.
