This question has a specific part and a general part. (BTW, I searched the forums about this and couldn’t find anything that seemed to match.)
The listing on Jisho for それぞれ has a couple of different kanji forms (e.g. the main one which is 夫れ夫れ), which intrigued me.
Specifically, it also says that this is covered in Wanikani Level 22. I thought, “Cool!” and searched WK for a variety of different forms of それぞれ and came up empty each time (respectively; それぞれ, I guess? ).
So I checked level 22, and scanned through it and the closest thing I found was 各々 which kinda means the same thing. The only thing about it is that 各々 reads as おのおの, not それぞれ, and the 各々 seems not to mention それぞれ anywhere, in any of its forms. And furthermore, Jisho’s post on それぞれ makes no mention of 各々 or おのおの.
Additionally, Jisho’s post for おのおの makes no mention of それぞれ, nor does it even mention that おのおの is covered in WK Level 22! Yet, strangely, searching Jisho for おのおの actually also lists それぞれ, even though おのおの doesn’t appear anywhere in that listing.
So, the specific question is: WTF?!
… Also, why doesn’t WK cover それぞれ, seeing as it’s JLPT N3, whereas おのおの isn’t even on JLPT?
And the more general question(s) is/are: Does this mismatch occur frequently between WK and Jisho (with different words/kanji)? Does it periodically get fixed, or is it continually getting corrupted over time? Etc.?
