Morphology

wild + orange

The compound is a straightforward composition of 'wild' (uncultivated, living in nature) + 'orange' (the orange tree/fruit), so a B1 learner who knows both words will readily infer it refers to an uncultivated or wild-growing orange tree (often with less edible/bitter fruit). There is no idiomatic or metaphorical shift—botanical specifics like use as rootstock are specialized information but do not block basic comprehension.

Etymology

The noun wild orange names a small tree with sweet-smelling flowers and orange-like fruit that is usually bitter and 'not for eating'. The name comes from the simple picture: wild because it grows on its own and orange because the fruit looks like an orange, and farmers often use it to help grow other orange trees.
