Morphology

subbase = base (transparent) = sub + base

The prefix 'sub-' clearly indicates 'under' or 'below', making the meaning of 'subbase' as a foundational base clear.

Etymology

The word subbase comes from the prefix sub- meaning 'under' and base meaning 'foundation' or 'bottom', as in subway or submarine. So a subbase is the low part that sits 'under' the base and gives support to the structure above it.
