supercharger: meaning, definition, pronunciation and examples

A supercharger is mechanically driven by the engine's crankshaft (via a belt or gear), providing immediate boost but using some engine power. A turbocharger is driven by exhaust gases, which makes it more efficient but can cause 'turbo lag' (a delay in response).

Yes, 'to supercharge' something means to greatly increase its power, intensity, or efficiency, both literally (an engine) and figuratively (a process or economy).

It is acceptable in business and technology journalism but remains somewhat informal and metaphorical. In formal academic writing, terms like 'catalyst', 'accelerant', or 'amplifier' might be preferred, depending on context.

It is a B2-level word. Learners interested in cars, engineering, or business/tech news will encounter it. Knowing the core mechanical meaning is most important; the figurative use can be deduced from context.

A device that forces extra air into an internal combustion engine to increase power output.
