Morphology

right + prism

The meaning is directly derived from combining 'right' (forming a 90° angle to a base) with 'prism' (a solid with two parallel bases): it denotes a prism whose lateral faces meet the bases at right angles so the sides are rectangles perpendicular to the bases. This adjectival-noun composition is a straightforward, compositional geometric term found across languages, so a B1 learner who knows both constituents can infer the meaning.

Etymology

Right prism comes from its parts: right meaning 'standing straight up' and prism meaning a solid with two equal, parallel flat ends. So a right prism is a prism whose side faces are rectangles that meet those flat ends at a 'right angle', which is why the name means a prism with sides perpendicular to the bases.
