Namaste, sometimes called namaskār and namaskāram, is a customary Hindu manner of respectfully greeting and honouring a person or group, used at any time of day. It is used in the Indian subcontinent, and among the Indian and Nepalese diaspora. Namaste is usually spoken with a slight bow and hands pressed together, palms touching and fingers pointing upwards, thumbs close to the chest. This gesture is called añjali mudrā; the standing posture incorporating it is pranāmāsana.

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.
