I keep on hearing the verb 鑑みる (かんがみる, “to take into account”）on the news in Japan. The kanji is on Wanikani level 31, with no kunyomi. After going through many kunyomi readings in the “hell” levels that I rarely hear in the wild, I think 鑑みる would be a useful addition to the vocabulary.
Unfortunately, the mods don’t actively monitor the forums or parts of them (not even “Feedback” or “Bugs” ) so you’d either need to tag them or shoot them an email at email@example.com or use the new chat feature during their office hours.
Just a reminder that Wanikani is not a vocabulary learning website, it’s a kanji learning website. The vocabulary is mostly there to reinforce readings and the context in which they are used. Of course you can always ask them to add something, but I don’t think there’s a high priority to make a complete and comprehensible vocab list.
If you’re looking for resources that do teach large, useful amounts of vocab, have a look at Torii or Kitsun.
To be fair, that’s usually what people say when someone suggests a word that uses readings that already appear a lot. This is a unique kunyomi, so it at least has that going for it. You won’t see it in any of the other items.
I am not sure I understand. Wanikani uses that they call “vocabulary” to introduce readings of the kanji that are not on the main “kanji” drills. I am just advocating for a reading to be added. It happens to belong to a verb and yes, you will learn new vocabulary, but the point is to learn a reading that is likely to come up in real life.
