Navigate, as an 8 letter course, is defined as the act of plotting a course or route. It is commonly used in the context of sailing, where it involves charting a course through the water, taking into account the wind, tides, and other factors. In other contexts, such as driving, navigating can involve plotting a route on a map or GPS device. Navigating is also used in the context of air travel, where it involves plotting a course through the sky, taking into account weather patterns, air traffic, and other factors.
