Morphology

planar = plane (transparent) = plane + ar

The adjective is a regular formation from 'plane' with the suffix '-ar' meaning 'relating to a plane', so the meaning is directly derived.

Etymology

Planar comes from the Latin word planus, which means 'flat', and it shares the same idea as the English word plane for a flat surface. So something planar lies on a flat surface, like a sheet of paper, and has two dimensions.
