The source provides an extensive explanation of the distinct but related concepts of swing path and swing direction in the game of golf. It clarifies that swing path is a broad term describing the clubhead's movement relative to the target line—categorized as inside-out, outside-in, or square—which dictates the general shape of the shot. Conversely, swing direction is a more specific, numerical measurement that quantifies the horizontal angle of this path at impact. The document stresses that understanding the interplay between these metrics and the clubface angle is essential for controlling ball flight and correcting common swing faults like slices and hooks, recommending the use of technology and targeted drills for improvement.
