Namaste (ˈnʌməsteɪ, Devanagari: नमस्ते), sometimes called namaskar and namaskaram, is a customary Hindu non-contact manner of respectfully greeting and honouring a person or group, used at any time of day. It is found on the Indian subcontinent, and among the Nepalese and Indian 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 pranamasana.
Namaste (Namas + te) is derived from Sanskrit and is a combination of the word namas and the second person dative pronoun in its enclitic form, te. The word namaḥ takes the sandhi form namas before the sound te.
It is found in the Vedic literature. Namas-krita and related terms appear in the Hindu scripture Rigveda such as in the Vivaha Sukta, verse 10.85.22 in the sense of "worship, adore", while Namaskara appears in the sense of "exclamatory adoration, homage, salutation and worship" in the Atharvaveda, the Taittiriya Samhita, and the Aitareya Brahmana. It is an expression of veneration, worship, reverence, an "offering of homage" and "adoration" in the Vedic literature and post-Vedic texts such as the Mahabharata. The phrase Namas-te appears with this meaning in Rigveda 8.75.10, Atharvaveda verse 6.13.2, Taittirya Samhita 2.6.11.2 and in numerous other instances in many early Hindu texts. It is also found in numerous ancient and medieval era sculpture and mandapa relief artwork in Hindu temples.
According to the Indologist Stephen Phillips, the terms "te and tvam" are an informal, familiar form of "you" in Sanskrit, and it is typically not used for unfamiliar adults. It is reserved for someone familiar, intimate, divine or a child. By using the dative form of tvam in the greeting Namas-te, there is an embedded secondary, metaphorical sense in the word. This is the basis of the pragmatic meaning of Namas-te, that is "salutations to the (divine) child (in your heart)", states Phillips.
