How to say "cube" in Japanese
Choosing the right word
- 立方体りっぽうたいnounThe dedicated word for a cube as a three-dimensional shape with six square faces, used in geometry and when describing the shape of an object.
- 角かくnoun, noun (suffix)Chiefly means corner, angle, or square; its 'cube' sense is marginal on its own, so for the three-dimensional shape this is seldom the word you want — use 立方体.
For a cube as a solid, three-dimensional shape, 立方体 is the word to reach for; 角 chiefly means corner, angle, or square, and only marginally covers the 'cube' sense.
