Morphology

trapezoidal = trapezoid (transparent) = trapezoid + al

The adjective is formed regularly from the noun 'trapezoid' plus '-al', meaning 'relating to' or 'having the shape of' a trapezoid.

Etymology

Trapezoidal comes from trapezoid, which goes back to the Greek word trapeza meaning 'table'. Imagine a table top with two sides longer than the others — that four-sided 'table' shape is a trapezoid, so trapezoidal means 'having that shape'.
