cab

The word 'cab' is a fascinating example of semantic evolution through abbreviation and technological change. It originated as a 19th-century shortening of 'cabriolet', the name for a light, two-wheeled, horse-drawn carriage with a folding hood. The carriage's name, borrowed from French, evoked its light, bouncing motion, likened to the leap of a goat. As horse-drawn carriages were replaced first by motorized taxicabs and then by the driver's compartments of large vehicles, the clipped form 'cab' seamlessly transferred its meaning to these new conveyances, retaining the core idea of a compartment for transporting people or for the vehicle's operator.

The word 'cab' is a simplex word. It is a shortened form of 'cabriolet', a type of horse-drawn carriage, borrowed from French in the 19th century. The French term derives from 'cabrioler', meaning 'to leap or caper', from Italian 'capriolare' (to leap like a goat), ultimately from Latin 'capreolus' (wild goat, roe deer).
