a little bit of foot work here-- (i looked at the Engrish site again-- hadn't in months and notices the sign on the door "Emergency Trap"-- it wa pointed out that Trap means stairs in dutch--and i realized, of course-- the Palisades of NJ use to be mined-- for Trap rock-- kind of fine basalt that forms steps...) i wanted to see if there was an other meaning of trap in English meaning stairs. i was thinking about a trap door, but while on the page of my M-W 10th, i tripped over trapezium-- and found a four footed table.. who'd a thought! trapeze and trapizoid come from the same roots..
