Etymology

From Middle English trappe, from Old English træppe, treppe (“trap, snare”) (also in betræppan (“to trap”)) from Proto-West Germanic trappjā (“trap, snare”), from Proto-West Germanic trappjan (“to step”), from Proto-Germanic trapjaną (“to tread, stamp”), from Proto-Indo-European drebʰ- (“to step, trip, trample”). Cognate with Dutch trap (“step, stair”), German Low German Trapp (“step, stair”). Akin also to West Frisian traap (“stepping, treading, stairway”), German Treppe (“step, stair”), Old English træppan (“to step, tread”). Connection to "step" is "that upon which one steps". French trappe and Spanish trampa are ultimately borrowings from Germanic.

Borrowed from Swedish trapp (“step, stair, stairway”), from Middle Low German trappe (“stair, step”).

Akin to Middle English trappe (“trappings, gear”), and perhaps from Old Northern French trape, a byform of Old French drap, a word of the same origin as English drab (“a kind of cloth”).

Clipping of trapezius.
