図形
ずけい · zukei · JLPT N2 · noun
figure
🔷 図 (zu) = drawing/diagram + 形 (kei) = shape: a figure is a drawn shape
図 means diagram or drawing, and 形 means shape or form. Put together, 図形 names any geometric shape or figure, such as a triangle or circle.
形 — open frame 开 + hair/pattern 彡
形 combines 开 (originally a phonetic element suggesting the sound) with 彡, a radical depicting fine lines, hair, or decorative strokes. The 彡 part conveys the idea of visible markings or surface appearance, giving 形 its core meaning of 'shape' or 'form.' Over time it broadened to cover physical figure, appearance, and abstract form.
