Etymology

Origin of cab¹

First recorded in 1640–50; short for cabriolet

Origin of cab²

First recorded in 1525–35; from Hebrew qabh

Explanation

A cab is a taxi, a car whose driver you pay to take you where you need to go. It can feel like a competitive sport to hail a cab in New York City. Your cab driver may talk incessantly while she drives you to the airport, or you might ride in a cab that's silent except for the sound of its horn honking at other drivers. You can also call the front part of a truck, where the driver sits, the cab. In the 1820s, the word meant "horse-drawn carriage," short for the French cabriolet, "leap or caper." The Latin root is capreolus, "wild goat."
