Morphology

substructure = structure (transparent) = sub + structure + sub

Meaning is directly derived from 'sub-' (under) + 'structure' (framework), indicating an underlying or supporting structure.

Etymology

The word substructure combines sub- meaning 'under', as in the word subway, and structure meaning 'something built or put together'. So a substructure is the part under a building or system that supports and holds it up.
