Morphology

Castile + soap

This is a toponymic compound: a B1 learner who knows 'Castile' (the region/name) and 'soap' can infer it denotes a type of soap from Castile. The precise production detail (made with olive oil) is more specific cultural knowledge, but the basic meaning 'soap originating from Castile' is transparently derived from the constituents.

Etymology

Castile soap comes from the Castile region of Spain, where people long ago made a hard soap using olive oil. Because it began as pure olive oil soap from Castile, the name now means a simple, 'gentle' soap made with olive oil.
