干预
gānyū · HSK 5
intervene
🛑 干 = dry/intervene + 预 = beforehand; step in ahead of trouble
干预 decomposes as 干 (to do/interfere) + 预 (in advance, beforehand). The combined sense: to act on something before it runs its own course — to intervene or meddle.
干 — pictograph of a forked weapon/shield
干 originally depicted a forked wooden weapon or shield used in ancient warfare, giving the early sense of 'to offend' or 'to oppose.' Over time it took on extended meanings like 'to concern' and 'trunk/stem.' In modern simplified Chinese it also absorbed 乾 (dry) and 幹 (to do; trunk), so one character now covers several unrelated words.
