means The art and practice of figuring out where you are and how to get where you're going, whether by sea, land, air, or menu screen.

from From Latin navigare, 'to sail a ship,' built from navis ('ship') and the root of agere ('to drive, to do'). Navis is an old seafaring word with deep cousins across Indo-European languages — Greek naus, Sanskrit nau — all pointing back to the boat. So 'navigation' began strictly as the business of driving a ship across water; only much later did it sail inland to cover cars, planes, websites, and the general act of not getting lost.
