訓

It is a phono-semantic compound, composed of:

言 (“speech, words”) — semantic element, indicates speech, explanation, verbal transmission

川 (cheon, “river”) — phonetic element

The combination expresses the idea of words flowing like a river - instruction, explanation.

The original sense of 訓 was "to instruct orally; to pass down guidance through speech."

From this, several closely related meanings developed:

- teaching and moral instruction

- explanation of words and meanings

- authoritative guidance passed from elders or scholars

Modern usage semantic range:

- teaching

- instruction

- moral guidance

- explanation of meaning

Connotation:

- formal

- educational

- often authoritative but not coercive

In modern and classical Korean, 훈 (訓) appears widely in the sense of teaching, instruction, or glossing:

교훈 (敎訓) — lesson, moral, instruction

훈계 (訓戒) — admonition, moral instruction

훈시 (訓示) — address, instruction (esp. by an authority)

훈고 (訓詁) — classical exegesis; explanation of word meanings

훈독 (訓讀) — “gloss reading,” the native-language semantic reading of a Chinese character (cf. 음독, On-reading)

訓民正音 (훈민정음) — “The Correct Sounds for the Instruction of the People,” the original name of the Korean alphabet Hangul

Thus, 訓 has both a pedagogical meaning (“to teach, instruct”) and a linguistic meaning (“semantic gloss”), making it central in both education and the history of the Korean script.

訓 is central to Korean intellectual history:

訓民正音 literally means “instruction of the people with correct sounds.” Emphasizes education, explanation, and accessibility of knowledge.

In classical studies, 訓 refers specifically to semantic explanation of words, especially archaic ones.

Example:

訓詁 — philological explanation of classical texts

This meaning survives strongly in Korean and Japanese linguistic tradition.
