Morphology

substratum = stratum (transparent) = sub + stratum

Formed by the productive prefix 'sub-' (under) plus 'stratum' (layer); the physical meaning 'under layer' is directly derived.

Etymology

Substratum comes from Latin parts sub- 'under' and stratum 'layer', so it literally means an 'under layer'. Think of a hidden layer of rock or soil beneath ancient ruins, and that's why substratum means the foundation beneath something.
