Morphology

undissipated = dissipated (transparent) = un + dissipate + ed

A straightforward negation of the adjectival sense 'dissipated' meaning 'scattered/dispersed', so the meaning 'not dispersed' is directly derived.

Etymology

Undissipated comes from dissipate, which means 'to scatter' or 'waste', and the prefix un- means 'not'. So undissipated is 'not scattered' or 'not lost', like heat or energy that stays inside a container.
