rainout singular

Morphology

rainout = rain + out (semi-transparent) = rain + out

The compound directly combines 'rain' and the sense of 'removal' conveyed by 'out', but the specific technical meaning (wet deposition of particles) is specialized.

Etymology

Rainout comes from rain and out, with the idea that rain takes things 'out' of the air and drops them on the ground. So in science a rainout is the process where rain removes dust, ash, or pollution from the air.
