Morphology

substantial = substance (transparent) = substance + ial

The meaning 'large in amount/important' is a standard, directly inferable extension from 'having substance' (being considerable or significant).

Etymology

Substantial comes from Latin sub- 'under' and stant- 'to stand', which gave us substance meaning 'real stuff' with weight or value. So a 'substantial' amount is a large or important amount — something with real weight or value.
