📖 訓 = 言 speech + 川 river: native words that explain what a kanji means
訓 originally meant to explain or instruct, and 川 also hints at its sound. A kun reading is the native Japanese word used to gloss a character, like 山 read as やま. The other kind of reading, on (音, sound), is the one borrowed from Chinese.
