Morphology

caper + spurge

The constituent 'spurge' signals a plant in the spurge family, so a learner who knows both words can plausibly infer this is a type of plant. However, 'caper' functions as a species-specific modifier with no transparent link to the detailed meaning (poisonous, seeds yielding purgative oil), and botanical names are largely lexicalized and unpredictable, so the overall interpretation is only partially recoverable.

Etymology

Caper spurge mixes two old ideas: spurge comes from a word meaning 'to purge' because people used the plant's milky sap as a strong medicine, and caper may come from the look of its seeds or leaves, like the caper plant. So, the name helps you remember it is a plant with a strong, often poisonous sap whose seeds were used as a 'purgative'.
