"pull with a rope," Old English togian "to drag, pull," from Proto-Germanic *tugojanan (source also of Old English teon "to draw," Old Frisian togia "to pull about," Old Norse toga, Old High German zogon, German ziehen "to draw, pull, drag"), from PIE root *deuk- "to lead" (source also of Latin ducere "to lead"). Related: Towed; towing.
"vehicle," 1610s, originally "small wheel" (especially one on which the carriages of a ship's guns were mounted), probably from Latin trochus "iron hoop," from Greek trokhos "wheel," from trekhein "to run" (see truckle (n.)). Sense extended to "cart for carrying heavy loads" (1774), then in American English to "motor vehicle for carrying heavy loads" (1913), a shortened form of motor truck in this sense (1901).
There have also been lost to the enemy 6,200 guns, 2,550 tanks and 70,000 trucks, which is the American name for lorries, and which, I understand, has been adopted by the combined staffs in North-West Africa in exchange for the use of the word petrol in place of gasolene.
