修繕
しゅうぜん · shuuzen · JLPT N2 · noun
repair
🔧 修 = fix + 繕 = mend; the 糸 (thread) radical hints at stitching things back together
修 means fix or repair, and 繕 means mend or patch. Its 糸 radical means thread, so the word covers both fixing and stitching. It is used for repairing buildings and other large objects.
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.
