Morphology

rush + nut

The meaning is directly compositional: 'rush' (a marsh plant) combined with 'nut' (an edible seed) denotes a nut-like tuber or edible part of a rush. This follows a regular noun+noun compounding pattern that a B1 learner who knows both constituents can infer.

Etymology

Rush nut may come from the plant's look: it grows among rush plants in wet places and has small, hard, round tubers like a nut. That's why the name today means 'a small edible tuber' from that marsh plant.
