Morphology

heath + pea

The noun–noun compound 'heath pea' transparently combines 'heath' (open uncultivated land) + 'pea' (a plant), so a B1 learner who knows the constituents would readily infer it denotes a type of pea associated with heathland. The specialized botanical details (small edible tubers, whisky flavoring) are additional encyclopedic facts but do not undermine the clear compositional meaning.

Etymology

Heath pea probably comes from a small plant that grows on the heath, meaning open wild land, and that has tiny, pea-like edible roots. People in parts of Scotland once gathered those roots as 'food' and to add a special 'flavor' to whisky, so the name links the place heath and the plant form pea to the plant's modern use.
