What are ON and KUN readings of the kanji?
@ON readings are the pronunciations of the characters as they sounded to Japanese ears when introduced to Japan (which is not to say that the ON readings in use today are exactly the same as their earliest forms). KUN readings are terms, native to Japan, that were assigned to kanji of the same or similar meanings. @Taking (water) as an example, the ON reading is “SUI” and the KUN reading “mizu.” Kanji can have multiple readings, both ON and KUN.
