The most common synonym for a taxi car is cab or taxicab, terms derived from the "cabriolet" (a horse-drawn carriage). In 2026, the terminology has expanded to include ride-share or e-hail when referring to services like Uber or Lyft. In specific regions, you might hear the term hack or hackney carriage, particularly in London, where it refers to the iconic black cabs. Other informal or regional synonyms include minicab (common in the UK for private hire vehicles), jitney (historically referring to small buses or shared taxis), and in some literary contexts, a conveyance. In the modern digital economy, many simply refer to the service as a ride, as in "I'll call a ride," reflecting the shift from vehicle-centric language to service-centric language where the car itself is a secondary consideration to the convenience of the app.
