Morphology
The compound is compositional: 'blight' denotes a plant disease and 'rim' denotes an edge or margin, so a B1 learner who knows both words can infer it is a blight affecting the leaf margins. The meaning is literal and follows transparent noun–noun modification patterns common across languages, so prior exposure is not required for understanding.
Etymology
The name rim blight comes from a simple picture: the rim, the leaf 'edge', turns yellow and brown because of a blight, a plant 'disease'. So, rim blight means a disease that makes the edges of leaves go yellow and brown.
