What 微 means
In modern Chinese, 微 adds a sense of smallness or subtlety.
微量 means “a tiny amount”; 微笑 means “smile”; 微妙 means “subtle.” Read a lone 微 in context.
What are 微’s older meanings?
Classical Chinese uses include “hidden,” “obscure,” decline, and “not.”
Han-era Shuowen, a Chinese dictionary, defines 微 as “walking secretly.” A study reads an ancestor of 微 in Wuding-era oracle-bone divinations—ritual questions carved on bone or shell—as a Zhou group name; that reading and its link to “small” are disputed.
Questions people ask
1Why does 微 show as a box on some devices?
Because that device's fonts have no glyph for it. The character is still correct and still copies correctly — the box is a missing glyph, not a broken character.
