微妙

subtle
🔬 微 tiny + 妙 wonderful = a difference too tiny to be obvious, yet clever: subtle
微 means micro or tiny (as in 微博 microblog), and 妙 means clever or marvellous. A subtle thing is a tiny, clever detail. Sound hook: miào rhymes with meow, the faint sound a cat makes when it wants something subtly.
妙 — woman radical 女 + few 少
妙 is a semantic-phonetic compound. 女 (woman) suggests delicacy or beauty, while 少 (few/young) provides the sound and hints at youthful slenderness. The original sense was 'subtle, delicate, exquisite,' later extending to 'wonderful' or 'marvelous.'
