Surface Forms

aerogel singular
aerogels plural

Morphology

aerogel = gel (transparent) = aero + gel + aero

The meaning is directly derived from the productive combining form 'aero-' (air) plus 'gel', indicating a gel in which air replaces the liquid.

Etymology

Aerogel comes from aero- meaning 'air', like in aeroplane, and gel meaning 'jelly', so an aerogel is like 'air-jelly', a material that is mostly air, which makes it very light and a good insulator.
