A truck is a large vehicle used for transporting bulk goods, materials, or equipment. The word "truck" comes from the Greek "trochos", meaning "wheel." In North America, the big wheels of wagons were called trucks. When the gasoline-engine driven trucks came into fashion, these were called "motor trucks." Lorry is a term from the UK, but is only used for the medium and heavy types, i.e. a van, a pickup or a Jeep would never be regarded as a "lorry." Other languages have loanwords based on these terms, such as the Malay language and the Spanish language in northern Mexico.
