anisotropic

Varies by orientation

Anisotropic describes materials or systems whose properties differ depending on the direction of measurement.

Wood is anisotropic—it splits easily along the grain but resists force across it.

The term appears in physics, materials science, and geology: anisotropic crystals, anisotropic conductivity.

The opposite is isotropic, meaning uniform in all directions.
