IELTSAcademic
noun

The quality of being different in different directions. In science, a material or process is anisotropic when its properties change with direction.

  • Wood shows anisotropy along and across the grain.
  • The crystal's anisotropy affects how light passes through it.

Adinary Nuance

Anisotropy is used in science and technical writing, not in everyday speech. It is more specific than words like difference or variation, because it means change with direction. If you want the opposite idea, use isotropy, which means the same in all directions.
