screw bean singular

Morphology

screw + bean

The noun is compositionally built from 'screw' (suggesting a spiral/helical shape) + 'bean' (a pod/seed), so the meaning ‘a spirally twisted bean pod’ is directly inferable from the parts. Although the specific botanical item is rare, the shape-based compounding follows normal English patterns and would be understandable to a B1 learner who knows the constituent words.

Etymology

Screw bean can also mean the sweet, spirally twisted pod of that tree, because the pod winds like a screw and contains edible seeds. People and animals ate or ground these pods into 'meal', so the word points to the pod used as food.
