Morphology

trapezohedron = trapezium + hedron (semi-transparent) = trapezo + hedron

The term literally combines the geometric element 'trapezium' (via the combining form 'trapezo-') with '-hedron' to indicate a solid, but both elements are technical combining forms that many learners may not recognise.

Etymology

Trapezohedron comes from the parts trapezo- and -hedron, where trapezo- points to trapezoid (a four-sided shape with at least one pair of parallel sides) and -hedron means 'face' or 'base' as in polyhedron, so a trapezohedron is a solid whose faces are trapezoids.
