干活儿
gànhuór · HSK 2
to work
🔨 干 = do/work + 活 = live/work + 儿 = -r suffix
干活 literally combines 干 (do, dry, trunk) with 活 (live, alive, work) — both characters mean 'work' here, doubling up. The 儿 suffix is the northern colloquial -r ending, making it casual speech for doing manual labor.
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.
活 — water radical 氵 + tongue 舌
Originally a phono-semantic compound: 氵 (water) suggests flowing or liveliness, while 舌 (tongue) hints at the sound. Early forms depicted gushing water, conveying the idea of being lively or alive. The meaning broadened from 'flowing water' to 'living, alive, active.'
