Components

radical
口 kǒu
mouth; small enclosure
Inner-bottom mouth radical - also 周's indexing radical (Kangxi #30). Carries the semantic anchor: the original sense was a fenced field (口 = small enclosure) holding grain in completeness. From 'all around' came 周围, 周末, 周朝 (Zhou dynasty), and the surname.
semantic
冂 jiōng
down-open frame
Outer frame 冂 - open at the bottom, outlining the boundary of the field/enclosure. Two strokes: left-falling + top-and-right-hook. Same frame appears in 用, 同, 网. The whole char is indexed under Kangxi #30 口 - the mouth-shape tucked at the base of the frame.
semantic
土 tǔ
earth; soil
Middle 土 - earth/ground inside the framed enclosure, completing the ancient picture of a planted field. Originally 周 showed grain on the soil within walled boundaries; the 土 is the cultivated land at the heart of 'completeness all around.'
