Morphology

inclined + plane

The meaning 'a sloping flat surface' is directly and transparently derivable from combining 'inclined' (tilted or sloping) with 'plane' (flat surface); it is a straightforward adjective + noun composition describing the object's shape and function. This compositional pattern is cross-linguistically common (e.g., Spanish 'plano inclinado', French 'plan incliné'), so an average B1 learner who knows both constituents would understand the MWE.

Etymology

The noun inclined plane comes from the simple image of a flat plane set at an angle, or inclined, like a ramp. Because the surface slopes, you can push or roll a heavy box up with less force than lifting it, so the term names the simple tool that helps move things.
