干扰
gānrǎo · HSK 5
interfere
📡 干 (dry/do) + 扰 (disturb) = actively meddle with something
干 carries the sense of 'engage/do to', and 扰 means 'disturb/trouble'. Together they describe actively meddling — like radio interference cutting into a signal. Sounds roughly like 'gone-rao', a rowdy intrusion.
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.
