不服
ふふく · fufuku · JLPT N1 · noun
dissatisfaction
不 — single pictograph; bird flying upward
Originally a pictograph in oracle bone script, traditionally interpreted as a bird flying up toward the sky and unable to come down, suggesting negation or refusal. Over time it became the standard negation word in Chinese, used before verbs and adjectives to mean 'not'.
服 — 月 (moon/flesh) + 𠬝 (kneeling figure with hand)
Originally depicted a hand subduing a kneeling person beside a boat (later simplified to 月), suggesting submission or service. The meaning extended from 'submit/serve' to 'clothing' (what one wears in service) and 'to take' as in medicine. The phonetic role of 𠬝 helps fix the reading fú.
