An Origamic Word™ is a word ...

... where all letters are axisymmetric in their capital form. These are the letters A, C, D, E, H, I, K, M, O, T, V, W, Y. The letters S, N and Z have rotational symmetry and are not allowed in Origamic Words™. Whether the symmetry axis is vertical or horizontal doesn't matter.

The are called Origamic™, because ...

... one half of the letter can be folded onto the other, as in origami, the Japanese paper-folding technique.
