Morphology

planform = plan + form (semi-transparent) = plan + form

The components 'plan' and 'form' are semantically relevant, but 'planform' is a specialized technical term (shape in plan view) that is not immediately obvious to an average learner.

Etymology

Planform comes from the parts plan ('a drawing or map') and form ('shape'), so it literally means the shape shown on a plan. That's why planform refers to the outline you see when you look down from above, for example the top view of a wing or a building.
