Morphology

undersurface = surface (transparent) = under + under + surface

The word is a straightforward prefixation of 'surface' with 'under-', yielding 'the lower side', which learners can derive from known parts.

Etymology

Undersurface comes from the simple parts under ('below') and surface ('outer side'). So the undersurface is the surface that is below something — the lower side of an object, like the bottom of a leaf or the under part of a table.
