On how to interact with each other
So that you don't get lost from where you're going to and you don't have to go to multiple places to find the one that you are looking for. I hope this helps. Although sometimes it's not necessary because you might know where the place is or someone else is leading you to it. I really hope I helped have a brainly day!! ;)
I believe the answer is: Navis
In English language, Navis mean ships. The root word come from the language that is commonly used by the sailors when describing how they steer their ships. (it's the main vehicles for long distance travels at that time). The words later on also used for other type of vehicles such as airplanes, or train.
