Here is a worksheet on the Latin word root port. It means “to carry.” Accordingly, you’ll find it at the base of frequently used English words like import, export, deport, and transport (which also contains the Latin root trans–across, through, change, beyond) and even comportment, which arises from the verb comport, “to behave in a manner conformable to what is right, proper, or expected.”
As we might put it more figuratively, comportment means how one carries oneself. As I recall, when I was in elementary school in the 1960s, my report card carried a section on comportment.
