Morphology

understructure = structure (transparent) = under + structure

Meaning is directly derived from 'under' + 'structure' indicating a supporting or lower structure beneath the main structure.

Etymology

Understructure comes from the parts under meaning 'below' and structure meaning 'building' or 'support'. So, an understructure is the base or foundation that lies under and holds up the main part of a building.
