Morphology
trapezoid = trapez + oid
Built from the Greek combining form 'trapez-' + the suffix '-oid' ('resembling'); the combining form is not a standalone English word, so the structure is partially clear but not fully transparent to average learners.
Etymology
Trapezoid comes from the Greek word trapezion, which means 'little table'. Think of a small four-legged table to picture a four-sided figure with one pair of parallel sides, and that image helps explain the shape we call a trapezoid.
