How to Write 椭 (tuǒ) — Meaning “Oval / ellipse”

Visualize a wooden board (木) being carved into an oval shape. The right part 隋 can be broken into 阝 (a slope), 有 (to have), and 月 (moon) — imagine a sloping surface that has a moon-shaped oval on it. This image links the components to the meaning "oval."

The left radical 木 should be narrow and written first (4 strokes). The right part 隋 is complex: write 阝 (2 strokes), then 有 (6 strokes), then 月 (4 strokes) — make sure the middle 有 is not too tall and the bottom 月 aligns vertically. A common mistake is making the 木 too wide or misplacing the strokes in 隋.

椭 (oval) has 木 on the left and 隋 on the right, while 柴 (firewood) stacks 木 on top of 此. 栓 (bolt) also has 木 on the left but with 全 on the right. Visually, 椭 is left-right with a complex right side, while 柴 is top-bottom and 栓 has a simpler right side. They have completely different meanings and uses.

椭 appears mainly in technical or geometric terms like 椭圆 (ellipse), 椭圆形 (oval shape), and 椭球 (ellipsoid). You might see it in math textbooks, engineering diagrams, or when describing the shape of an egg or a sports field. It is not used in everyday conversation but is important in science and design contexts.

Common words containing 椭 include: 椭圆 (tuǒ yuán) — Ellipse; 椭圆形 (tuǒ yuán xíng) — Oval shape; 椭球 (tuǒ qiú) — Ellipsoid.
