means A dense, tall forest in a wet tropical or temperate region that gets so much rain year-round it supports an extraordinary density and diversity of life.

from A straightforward compound of 'rain' and 'forest' — no hidden trick here. The term is generally credited to late-19th-century botanists translating German 'Regenwald,' coined to describe forests where rainfall is so constant and heavy it shapes the entire ecosystem. The phrase simply names the obvious: forest, made by rain, over and over, for millennia.
