Just to add on to this, what someone said earlier:
Unlike English kanji have associated ideas that Wanikani calls readings
If we’re simplifying the concept of kanji to be like English letters, then I still like to see English letters as having ‘readings’.
In the above sentence ‘e’ can be read as:
‘eee’ → ‘we’, ‘be’, ‘English’
‘eh’ → ‘letters’, ‘then’
And the way I usually simplify the whole concept is:
Radical → Standalone ‘drawing’, doesn’t mean anything but is given a name to help you remember.
Kanji → A ‘letter’, made up of 1 or more drawings (radicals). WaniKani typically teaches the most common/useful reading for this. But, all of the readings are still valid for that kanji, even the ones WaniKani doesn’t accept in the answer. The reason WaniKani does this is to expose you to more ways to read the kanji, and you can then learn which reading to use with each word.
Vocab → A ‘word’, made up of 1 or more letters (kanji). Uses one of the readings per each letter.
Drawings make up letters which make up words.
Let’s imagine English is being taught as Japanese.
You might start with something like this:
(apologies for my awful drawing of a cane lol)
And let’s say the reading you’re taught for this is ah, because let’s hypothetically say it’s the more common reading.
And then, you’re taught the vocabulary word:
And what do you know, the dictionary word ‘a’ has the reading ey which is what you’re taught.
So, the letter (kanji) has readings ah and ey, but you’re specifically taught to answer ah, even though any of the readings would still be correct for this letter.
The vocab word that only has this one ‘kanji’ uses the reading you weren’t taught with the letter - ey.
Then, you may be taught another vocab comprising of three ‘kanji’ - a, r, and e - are. Here, you still see the ah reading of the ‘kanji’.
To summarise:
circle → drawing (radical)
cane → drawing (radical)
a → letter (kanji) made up of 2 drawings (radicals). Has readings
ahandeybut you’re taught to answerahfor the kanji.a → a vocab word made up of 1 letter (kanji). The word uses the
eyreading.are → a vocab word made up of 3 letters (kanji). Here, the letter (kanji) uses the
ahreading.
Relate It Back To Japanese
Japanese is, of course, a bit more complicated because kanji have associated meanings, but I think this simplification still helps understand how each of the 3 things relates to each other and why WaniKani teaches it a certain way.
水 → a drawing (radical).
水 → a letter (kanji) made up of 1 drawing (radical). Has readings
すいandみずbut you’re taught to answerすいfor the kanji.水 → a vocab word made up of 1 letter (kanji). The word uses the
みずreading.水中 → a vocab word made up of 2 letters (kanji). Here, the letter (kanji) uses the
すいreading.
This is how my brain works, hope this helps someone ![]()
