circumnavigate (v.)

word-forming element meaning "around, round about, all around, on all sides," from Latin adverb and preposition circum "around, round about," literally "in a circle," probably accusative form of circus "ring" (see circus). The Latin word was commonly used in word-formation. In French, the element became circon-; Kitchin points out that con for cum is common even in classical Latin. For sense development, compare German rings "around."

1530s, "act of moving on water in ships or other vessels," from French navigation (14c.) or directly from Latin navigationem (nominative navigatio) "a sailing, navigation, voyage," noun of action from past-participle stem of navigare "to sail, sail over, go by sea, steer a ship," from navis "ship" (from PIE root *nau- "boat") + root of agere "to set in motion, drive, drive forward" (from PIE root *ag- "to drive, draw out or forth, move"). Meaning "science or art of directing the course of vessels as they sail" is from 1550s.

The management of the sails, etc., the holding of the assigned course by proper steering, and the working of the ship generally pertain rather to seamanship, though necessary to successful navigation. The two fundamental problems of navigation are the determination of the ship's position at a given moment, and the decision of the most advantageous course to be steered in order to reach a given point.
