ㄩㄢˊ · yuán
noun/adj — round; a circle; complete, whole
字源 FORM — what the parts do
囗形the enclosing boundary
A boundary (囗) drawn all the way round. 員 yuán carries the sound, and it is itself round — a pot's mouth viewed from above. So the box encloses what is already round. From the closed circle: 圓圈、圓滿. It builds the 員 series: 損、隕、圓.
