Morphology

planarity = planar (transparent) = planar + ity

A straightforward nominalization from the adjective 'planar' indicating the state or quality of being planar.

Etymology

Planarity comes from the Latin root planus, meaning 'flat', and the English word plane for a flat surface, with the ending -ity meaning 'quality' or 'state'. So planarity means the quality of being flat or existing in a single plane, which is why we use it for flat glass, metal, or surfaces in engineering and math.
