Morphology

rain + forest

The meaning 'a dense forest characterized by high rainfall' is directly and transparently derived from the constituents 'rain' (water falling from the sky) and 'forest' (a large area of trees); a B1 learner who knows both words can infer this compound meaning. This noun-noun compounding pattern is common in English and cross-linguistically parallel, so the MWE is immediately comprehensible despite orthographic variation (rainforest vs. rain forest).

Etymology

Rain forest comes from the simple image of a forest that gets heavy rain most of the year, so trees and plants grow very thick and green. That's why 'rain forest' means a very dense forest in warm tropical areas that gets a lot of rain.
