Jeep is a brand of car made by the company Daimler-Chrysler. This word is associated with rather a military vehicle that was built for the United States Army in World War II, which took place below a model more suitable for daily consumption, which remained that name.
The origins of the term “jeep” are not very clear. Generally this is called a deformation in the phonetic pronunciation of its name initial GP General Purpose (“generally useful” in English) that eventually became “Jeep”. R. Lee Ermey declared that the vehicle is designated for specific purposes, and that the acronym was not referring to the “general utility”, but can be derived from the nomenclature for the Ford car in which the letter “G” indicated it was a government car use, and “P” to the size of the axes of the wheels.
However, some people, including Mr. Ermey, claim that the most likely source of a good character in the Popeye comic strip known as Eugene the Jeep (the original version in English).
This character could walk through walls and vertically to the wall, drill through the trees, fly, and anything else you wanted to, and as soldiers are supposed to be impressed by the versatility of the vehicle then named the character informally.
