Morphology

dry + rot

The components 'dry' (not wet) and 'rot' (breakdown by microbes) together suggest a kind of decay associated with dryness, so a B1 learner could plausibly infer this is a form of wood decay. However, 'dry rot' is a specific, somewhat technical and paradoxical diagnosis (rot that affects apparently dry wood), so the precise pathological meaning is not fully predictable from the parts alone.

Etymology

Dry rot comes from what people saw when a fungus attacked wood: the wood looked very dry and crumbled into powder. The words dry and rot show that picture, so today dry rot means 'a fungus that makes wood dry, crumbly and weak'.
