Early manufacturers of turbochargers referred to them as “turbosuperchargers”. A supercharger is an air compressor used for forced induction of an engine. Logically then, adding a turbine to turn the supercharger would yield a “turbosupercharger”. However, the term was soon shortened to “turbocharger”. This is now a source of confusion, as the term “turbosupercharged” is sometimes used to refer to an engine that uses both a crankshaft-driven supercharger and an exhaust-driven turbocharger.

Some companies such as Teledyne Continental Motors still use the term turbosupercharger in its original sense.

A turbocharger, or turbo, is a gas compressor that is used for forced-induction of an internal combustion engine. A form of supercharger, the purpose of a turbocharger is to increase the density of air entering the engine to create more power. However, a turbocharger has the compressor powered by a turbine, driven by the engine’s own exhaust gases, rather than direct mechanical drive as with many other superchargers.
