Morphology

yam + bean

This is a straightforward noun–noun compound whose meaning (a plant associated with yams and beans, i.e. an edible root-producing leguminous/tuberous plant) can be inferred from the constituents. The referent is compositional and follows common naming patterns for plants, so a B1 learner who knows "yam" and "bean" would reasonably guess it denotes a plant with yam-like edible roots.

Etymology

The name yam bean may come from a simple picture: a climbing bean plant that makes a large, edible yam-like root, so people put the two words together. That's why the name means a 'bean plant grown for its edible root'.
