A combustion turbine does not equal an engine (in aerospace terms, at least) If an engine has any worth, it’ll have a compressor before the combustor and the engine.
@garryn You’re right but when you add context a jet engine is a jet engine and a car engine (was for many years a car engine). Even the new hybrid gas electrics are still an engine and I don’t even entirely know how they work. They work.
In addition our common use of engine allows for understanding on a gradient. A driver needs only know that the car is powered by an engine. An enthusiast or someone looking for deeper understanding might want to know what type be it diesel, petrol or ethanol powered. A tech will want to know even more detail and want/need more accuracy in definition.
We all start out with an engine and some will never need to move beyond the simple. In other parts of life we are surrounded by simple names for things for broader reference but specific names for deeper understanding, clarification and specificity.
Animals: Ape, chimpanzee, Pan troglodytes
In this example ape is a broad vague term but holds meaning. This could be Gorillas, Chimps or humans but doesn’t mean monkey, fish or car. Lots of people have a basic concept of an ape so they’ll get when we say ape.
Chimpanzee further defines and offers more specificity ruling out all other apes while still being an ape. People will still get it but some people don’t the difference between chimps and gorillas or chimps and orang utans.
Finally we have the scientific classification name for a species of chimpanzee Pan troglodytes. Its more specific and even more accurate but fewer people actually know what it means, haven’t even a vague concept of the thing. A few specialists, primatologists, zoologists and other -ologists might know what it is.
It makes sense then to use the least specific term required to make it clear to the intended audiences and layer detail and clarification through definition as opposed to using the highest level term and decrease the detail through definition.
