Learn each reading together with a complete word and its meaning.

The idea

On readings derive historically from Chinese pronunciations; kun readings represent native Japanese words. 山 is やま alone but さん in 富士山; 水 is みず alone and すい in 水曜日. Compounds often use on readings, while standalone words often use kun readings.

Watch out

These are tendencies, not reliable rules: 本 is ほん even alone, and 日本 is にほん. Some words mix readings or have special readings. Check the whole word in a dictionary.
