The term 'changes course' can be defined as altering the direction of a journey or action. This can be done in various ways, such as zigging (4 letters), turning (5 letters), veering (5 letters), tacking (5 letters), jibing (5 letters), and redirecting (9 letters). Zigging involves making a sharp turn to the left or right, while turning is a more gradual change in direction. Veering is similar to turning, but it is usually done more quickly and with more force. Tacking is a sailing maneuver that involves changing direction by zigzagging into the wind. Jibing is a sailing maneuver that involves turning the boat's bow through the wind. Finally, redirecting is the act of changing the course of something, such as a conversation or a plan.
