Inspired by Koichi sticks, I’ve been trying to tie together words that have the same onyomi into my mnemonics. It starts to stick, because the story grows as I learn new words with same reading.
LIFE is strange in the BLUE WEST, for instance, started out as “Life is strange in the West” before i learned the kanji “Blue”. They all have “SEI” as onyomi.
As a first step, I can search jisho.org, but I’d like to see a site that does this for me… Anyone know?
The Semantic-Phonetic Script includes a section for each kanji which highlight on’yomi similarities and phonetic components of kanji, right here on WaniKani! If you want an organized resource of kanji and their phonetic similarities, check out this MA thesis paper which has a large chart of phonetically related kanji starting at page 37. It’s also an interesting read, if you’ve got some time.
