The names for the radicals are certainly helpful for remembering mnemonics, but I don’t like how only the mnemonic names are acceptable for answering the radical names. We should be able to use the actual meaning or Japanese name of the radicals as acceptable answers. I’m sure the staff is already familiar with their names and meanings, but here are some resources for those not in the know Here or Here . Personally, I’m not sure how hard this would be to implement, but I’d very much be interested in seeing it done.
P.S. I am aware that many of Wanikani’s names line up with, or relate to the actual radical meanings.
