Taxi vs. Cab
“Taxi” and “cab” overlap for a car with a paid driver, but “cab” also has other vehicle-compartment meanings. In the passenger-vehicle sense, the words are generally interchangeable.
Use “taxi” or “cab” for the paid-driver vehicle sense; “cab” is shorter and also has unrelated vehicle meanings.
Key details
Choose the right form
| Meaning | Use | Decision |
|---|---|---|
| a hired passenger vehicle with a driver | taxi or cab | Either word fits the documented passenger-vehicle sense. |
| the driver compartment of a truck, locomotive, or similar vehicle | cab | Use “cab”; “taxi” does not name this compartment sense. |
| you see “cab” without enough context | check the surrounding vehicle meaning | Do not assume every “cab” means a taxi. |

“Cab” has the same paid-driver vehicle sense here.

Here “cab” means the driver compartment, not a taxi.
