Morphology
This is a straightforward compound in which the modifier 'kola' specifies the type of 'nut', so a learner who knows both constituents can infer it is the seed of the kola tree. The meaning is concrete and compositional (a nut from a kola tree) rather than idiomatic, and such noun–noun naming patterns are cross-linguistically common, making it transparently interpretable.
Etymology
Kola nut is the bitter brown seed of a West African tree (the kola) that people chewed to feel more awake and to greet visitors. Its caffeine and strong flavor were used in early recipes for 'cola' drinks, so the name now means both the seed and the flavor used in beverages.
