Greeting with a gesture can be done by saluting, which is a six-letter word. Saluting is a common form of greeting in the military, where it is used to show respect and honor. It is also used in other contexts, such as when greeting a superior or a dignitary. Saluting involves raising the right hand to the forehead, with the palm facing outwards. This gesture is often accompanied by a verbal greeting, such as 'Good morning' or 'Good afternoon'.
