> Turboprops are jet engines

They are certainly turbine engines, but I thought "jet" was reserved for those engines that propel the vehicle solely by their exhaust stream and bypass air. I am willing to be told I'm wrong, though.

Turbofans are by your own definition jet engines. It's just that the bypass air is much larger.

I think you meant turboprop there, but the distinction I notice is that one has all propulsive airflow inside the nacelle, and one does not.

Agh. No, I meant turbofan, but I misread your post and actually completely agree with you - turboprobs are not jet engines.

Ha! It happens. Enjoy your weekend.
