不調
ふちょう · fuchou · JLPT N1 · noun
condition
fu (不, not) + chou (調, tune/order): a tune that's off, so things are out of tune and not running right.
不 means 'not' and 調 means 'tune' or 'condition', so 不調 is a condition that is not in tune. Use it for a body or machine that is off form.
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'.
