研修
けんしゅう · kenshuu · JLPT N2 · noun
training
🥋 研 = polish + 修 = refine, so 研修 = polish and refine your skills
研 means grinding a stone smooth and 修 means repairing or cultivating. Together they describe structured training that sharpens a skill over time.
修 — 亻 person + 攸 (phonetic) + 彡 hair/decoration
修 combines 攸 (a phonetic component originally showing a person being washed) with 彡, which depicts flowing hair or ornamental strokes. The 彡 element suggests grooming, polishing, or adorning, giving 修 its core meaning of cultivating, repairing, or refining oneself or things.
