Morphology

Wollaston + prism

‘Wollaston’ is an eponym/proper name without independent lexical meaning, while ‘prism’ clearly denotes an optical device, so a learner who knows both words can infer this is a particular kind of prism. The specific technical function (two calcite prisms cemented to produce plane‑polarized light) is specialized and not predictable from the constituents, making the expression only partially transparent to B1 learners.

Etymology

The noun Wollaston prism is named after the scientist William Hyde Wollaston. He joined two crystal prism pieces so a beam of light splits into two rays with different directions. This two-prism design produces 'plane-polarized light', so the name refers to a device that makes that kind of light.
