completely
💯 完 (complete) + 全 (whole) = completely whole
完 means finish or complete; 全 means whole or entire. Stacking two near-synonyms intensifies the sense, so 完全 reads as totally/absolutely — every part accounted for, nothing left out.
完 — roof 宀 + yuán 元 (phonetic)
完 is a semantic-phonetic compound: the roof 宀 suggests a house or enclosure, while 元 supplies the sound 'yuán/wán'. Originally it meant a building that was intact or whole, and the sense broadened to 'complete, finish, whole'.
全 — enter 入 on top + jade 玉
Originally written as 入 (enter) over 玉 (jade), depicting a complete, unflawed piece of jade kept in storage. From this image of a perfect jade came the meanings 'whole,' 'complete,' and 'entire.' The top component is sometimes written as 人.
