When it comes to navigation, the phrase "lay a course" is commonly used to express the act of charting a direction to follow. However, there are a multitude of different ways to describe this action using alternative synonyms. Some examples include plotting the course, setting a path, charting a route, mapping out a trail, establishing a direction, marking a way, determining a heading, or even simply choosing a course to take. Regardless of which term is used, the implication remains the same- that careful planning and foresight are necessary for successful navigation and travel.
