Morphology

rainfly = rain + fly (transparent) = rain + fly

The meaning is directly derivable from 'rain' + 'fly' where 'fly' denotes a flap or cover, so it clearly refers to a cover for rain protection.

Etymology

Rainfly combines rain and fly, where fly here means 'a sheet that hangs over something' like a small roof above the tent. So a rainfly is the waterproof sheet that covers a tent to keep rain out.
