The kanji "訓" is a phono-semantic compound (形声文字 けいせいもじ). The left side is "言" げん, which means "speech" or "words." The right side is "川" かわ, which means "river." This kanji originally depicts a person speaking, especially for explaining. The part of 川 is used phonetically to indicate the sound "kun" from the original word. Therefore, the character collectively represents the act of speaking or teaching, hence the meaning "instruction."
