Morphology

wall + rue

The compound is compositional: 'wall' specifies the habitat or location and 'rue' names a plant, so a learner who knows both words can infer this is a rue-like plant associated with walls. This noun–noun pattern (modifier indicating type or location) is a regular, cross-linguistically common composition, making the meaning accessible to B1 learners who know the constituents.

Etymology

Wall rue gets its name from where it grows: small, delicate ferns that cling to stone walls. The second word, rue, is an old name for a plant, so the name paints the picture of a 'tiny fern on a wall', which is why it means this little fern that grows on walls.
