Morphology

insubstantial = substantial (semi-transparent) = in + substant + ial

The negative prefix 'in-' combines straightforwardly with 'substantial' to mean 'not substantial'.

Etymology

Insubstantial starts with in- meaning 'not' and its main part is substance, which means 'stuff' or a 'solid thing'. So insubstantial means 'not having much substance', and that is why it describes a light, not filling meal or a weak idea.
