Meaning
The kanji 訓 covers several related meanings, all tied to the idea of guidance through language: instruction, teaching, precept, moral lesson, and reading. That last meaning refers specifically to reading a kanji in its native Japanese pronunciation. Most learners first meet 訓 through 訓読み — the native Japanese reading of a kanji, as opposed to the Chinese-derived 音読み.
Structurally, 訓 is a 10-stroke kanji taught in Grade 4 of Japanese elementary school. It uses the radical 言 (ごんべん) — the speech radical — on the left. The right-hand component echoes the shape of 川 (かわ), the character for river, with three parallel downward strokes.
Put the two halves together: words (言) flowing like a river (川), a steady stream of instruction from teacher to student. In classical Chinese and literary Japanese, 訓 referred to moral precepts passed from authority figures — rulers to subjects, parents to children, masters to apprentices. That sense of inherited, hierarchical wisdom still shapes how the kanji is used today.
One irony worth noting: in 訓読み, the kanji 訓 is actually read with its on'yomi クン, not its kun'yomi. Learners who notice this tend to remember it immediately.
Readings
On'yomi (音読み) — Chinese-derived readings
訓 has one primary on'yomi reading:
クン (KUN) — Used in nearly all formal compounds containing 訓. It derives from the Chinese pronunciation and appears across educational, institutional, and linguistic vocabulary. When 訓 combines with another kanji, expect this reading.
- 訓練 (kunren) — training, drill; structured practice to build a skill or discipline
- 教訓 (kyōkun) — lesson, moral teaching; wisdom drawn from experience or hardship
- 訓示 (kunji) — official instructions given by a superior to those below
- 訓読み (kunyomi) — the native Japanese reading of a kanji character
Kun'yomi (訓読み) — Native Japanese readings
訓 has one kun'yomi in standard usage:
よ.む (yo.mu) — In linguistic contexts, this means "to read a kanji in its native Japanese pronunciation." The dot marks where the stem よ ends and the inflectional ending む begins. This reading appears mainly in academic writing about kanji pronunciation.
- 訓で読む (kun de yomu) — to read (a kanji) using the kun reading
- 訓じる (kunjiru) — to read or interpret (literary/archaic form)

Memory Tip
Split 訓 into its two visible parts: 言 (ことば) on the left for speech, and three downward strokes on the right that mirror 川 (かわ), a river. A teacher's words flow like a river — steady, patient, shaping everything downstream. That image covers both core meanings: sustained instruction, and the native Japanese reading that flows from within the language itself (訓読み).
