Sorry, simple foul tip question

[Dholloway1962]

a foul tip is a batted ball that goes sharp and direct from the bat to the catcher’s hands and is legally caught by the catcher.

Many fans, catchers, and coaches mistakenly use the term "foul tip" to describe any pitch at which the batter swings and makes slight contact, regardless of whether it is caught by the catcher.

It is not a foul tip if it first touches anything other than the catcher's hand or glove, or if it is not legally caught and held by the catcher. In such cases the pitch is a foul ball and not a foul tip. If the pitch touches the ground before reaching the batter, it can no longer be legally caught and therefore cannot be a foul tip; if the batter then swings and nicks that ball with his bat, it would be an ordinary foul ball and not a foul tip, even if held by the catcher.
