So after getting to lvl 60 in Wanikani, I’ve been creating my own Anki lists from unknown words while reading short novels. I will usually create my own mnemonics, as I have found this method really helps me remember things. However, when I come across kana-only words ie. ぐにゃり, じりじり etc. there are no kanji in these words and it’s taking forever to commit to memory.
My question is, what are some good tricks to memorisng these kana-only words?
