I was reading the artical you posted, and it actually explains a lot about why the radicals are not the same as the ~214 radicals you talk about.
I didn’t find the number 214 mentioned in the article so I’ll assume you got that from another source about radicals.
First, you need to learn what a radical is. There’s a chance you’ve heard of radicals before – perhaps in reference to looking up kanji in paper kanji dictionaries – but those aren’t quite the radicals we’re talking about.
In this guide, radicals are patterns and symbols that appear inside each kanji. Each kanji consists of 1–3 (sometimes four) individual radicals. Think of them as “building blocks” for creating kanji.
That says that the radicals are not the same radicals you have encounter other places. Next the author explains why there are more and how you use then as mnemonics.
In the other radicals systems these are only five “radicals”, i.e. 3 different shapes for the same radical man, etc. WaniKani gives each shape of “man” it’s one name to use in unique mnemonics to make everything easier to picture/remember. You can see how these 5 “radicals” become 12 WaniKani “radicals”. WaniKani also adds radicals made up of whole kanjis I think. Either way you can see how 200+ can become 1000+.
I know this isn’t what you were expecting but I hope you stay and give it a try.
I do think that they explain in the article that this is a Kanji learning system and will not teach you the standard dictionary radicals. I honestly recommend you reread the article you link to. Anything we say is just a rewording of that article for the most part…
