Greeting is an act of communication in which human beings intentionally make their presence known to each other, to show attention to, and to suggest a type of relationship or social status between individuals or groups of people coming in contact with each other. Greetings are sometimes used just prior to a conversation or to greet in passing, such as on a sidewalk or trail. While greeting customs are highly culture- and situation-specific and may change within a culture depending on social status and relationship, they exist in all known human cultures. Greetings can be expressed both audibly and physically, and often involve a combination of the two. This topic excludes military and ceremonial salutes but includes rituals other than gestures. A greeting, or salutation, can also be expressed in written communications, such as letters and emails.

Ahoy is a signal word used to call to a ship or boat, stemming from the Middle English cry, 'Hoy!'. The word had fallen into obsolescence before rising from obscurity as the sport of sailing rose in popularity. 'Ahoy' can also be used as a greeting, a warning, or a farewell.

Bowing is the act of lowering the torso and head as a social gesture in direction to another person or symbol. It is most prominent in Asian cultures but it is also typical of nobility and aristocracy in many European countries. It is also used in religious contexts, as a form of worship or veneration. Sometimes the gesture may be limited to lowering the head such as in Indonesia, and in many cultures several degrees of the lowness of the bow are distinguished and regarded as appropriate for different circumstances. It is especially prominent in Nepal, India, Thailand, Laos, Vietnam, China, Korea, Japan, where it may be executed standing or kneeling. Some bows are performed equally by two or more people while others are unequal – the person bowed to either does not bow in return or performs a less low bow in response. A nod of the head may be regarded as the minimal form of bow; forms of kneeling, genuflection, or prostration which involves the hands or whole body touching the ground, are the next levels of gesture.
