Morphology

anisotropy = isotropy (transparent) = an + isotropy

Formed by adding the negative prefix 'an-' to 'isotropy', giving the straightforward opposite property (not isotropic).

Etymology

Anisotropy comes from Greek parts an- 'not', iso- 'equal' and -tropos 'direction' or 'turn'. So anisotropy means something is 'not equal' in different directions, for example a material that behaves one way along one axis and another way along a different axis.
