Morphology

jack + pine

The head noun 'pine' clearly signals a pine tree, so a B1 learner who knows both constituents would likely infer this is a type or variety of pine. However, the modifier 'jack' functions mainly as an arbitrary label/name rather than contributing predictable semantic features of the species, so the precise meaning (slender, medium-sized, eastern North America, etc.) is not derivable from the parts. This pattern (noun+noun species names) is cross-linguistically common, giving partial but not full transparency.

Etymology

Jack pine comes from the word jack, used for something 'small' or 'common', and pine for the tree. Because these pines often grow in poor soil and look short and twisted, people called them jack pines, and that name stuck.
