extended-cab

The compound "extended-cab" is a modern automotive term that logically describes its physical design. The first element, "extended," derives from the Latin verb 'extendere', meaning to stretch out, which entered English via Old French to describe something made longer. The second element, "cab," is a shortened form of "cabriolet," a type of carriage, whose name humorously originated from the Latin 'caper' for goat, evoking a bouncing motion. In the 20th century, "cab" became the standard term for the driver's compartment in trucks and taxis. Thus, "extended-cab" literally means a truck with a cabin that has been stretched or enlarged beyond the standard configuration to provide additional passenger or storage space.

Structure: extended (stretched) + cab (compartment) - extended: From Latin 'extendere' (to stretch out). A past participle functioning as an adjective meaning lengthened or enlarged. - cab: A clipping of 'cabriolet', from French, ultimately from Latin 'caper' (goat), referring to a light carriage. Functions as a noun meaning the driver's compartment, here generalized to the truck's passenger cabin.
