The word "taxi" is a contraction of the term "taxicab," which itself is a combination of two words: taximeter and cabriolet. The "taximeter" was an instrument invented in the late 19th century (from the German taxameter) to measure the distance traveled and calculate the "tax" or fare. The word "tax" comes from the Latin taxare, meaning "to charge." A "cabriolet" was a light, two-wheeled, horse-drawn carriage used for hire in 18th-century France, named after the French word cabrioler ("to leap or caper") because of the vehicle's bouncy movement. In 1907, Harry Nathaniel Allen of New York imported 600 gas-powered vehicles from France and coined the term "taxicab" to describe them. Over time, the phrase was shortened to just "taxi." In 2026, while the technology has shifted to digital apps and electric autonomous vehicles, the etymological roots remain tied to the historical "measure of the charge" for a "leaping carriage."
