"Lorry" has a more uncertain origin, but probably has its roots in the rail transport industry, where the word is known to have been used in 1838 to refer to a type of truck (a goods wagon as in British usage, not a bogie as in the American), specifically a large flat wagon. It might derive from the verb "lurry" (to carry or drag along, or to lug) which was in use as early as 1664, but that association is not definitive. The expanded meaning of "lorry", "self-propelled vehicle for carrying goods", has been in usage since 1911.
