Namaste (//, Hindi: [nəməsteː] ( listen))), sometimes spoken as Namaskar, Namaskaram is a respectful form of greeting in Hindu custom, found on the Indian subcontinent mainly in India and Nepal and among the Indian diaspora. It is used both for salutation and valediction. 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 or Pranamasana.
Etymology, meaning and origins
Namaste (Namas + te, Devanagari: नमस् + ते = नमस्ते) is derived from Sanskrit and is a combination of the word nama and the second person dative pronoun in its enclitic form, te. The word namaḥ takes the Sandhi form namas before the sound t.
Namaḥ means 'bow', 'obeisance', 'reverential salutation' or 'adoration' and te means 'to you' (singular dative case of 'tvam'). Therefore, Namaste literally means "bowing to you".  In Hinduism, it also has a spiritual import reflecting the belief that "the divine and self (atman, soul) is same in you and me", and connotes "I bow to the divine in you".
A less common variant is used in the case of three or more people being addressed namely Namo vaḥ which is a combination of namaḥ and the enclitic 2nd person plural pronoun vaḥ. The word namaḥ takes the Sandhi form namo before the sound v.
The gesture is widely used throughout India, Nepal, Bangladesh, parts of Asia and beyond where people of South and Southeast Asian origins have migrated. Namaste or namaskar is used as a respectful form of greeting, acknowledging and welcoming a relative, guest or stranger. In some contexts, namaste is used by one person to express gratitude for assistance offered or given, and to thank the other person for his or her generous kindness.
Namaskar is also part of the 16 upacharas used inside temples or any place of formal Puja (worship). Namaste in the context of deity worship, conclude scholars, has the same function as in greeting a guest or anyone else. It expresses politeness, courtesy, honor, and hospitality from one person to the other. It is used in goodbyes as well. This is sometimes expressed, in ancient Hindu scriptures such as Taittiriya Upanishad, as Atithi Devo Bhav (literally, the guest is god).
In the Hindi and Nepalese speaking populations of South Asia, both Namaste (//, ; Devanagari: नमस्ते) and Namaskar are synonymously used. In Nepal, people generally use Namaskar for greeting and respecting their elders. In Odia namaste is also known as ନମସ୍କାର (namaskār) General greeting[Hello-Namaskar]. In Kannada, Namaskara (ನಮಸ್ಕಾರ) for singular and Namaskaragalu (ನಮಸ್ಕಾರಗಳು) is used. In Telugu, Namaste is also known as Dandamu (దండము) or namaskaram (నమస్కారం) for singular and Dandaalu or namaskaralu for plural form.pranamamu (ప్రణామము) is also used in formal Telugu. In Bengali, the Namaste gesture is expressed as Nōmōshkar (নমস্কার), and said as Prōnäm (Bengali: প্রণাম) informally. In Assamese, Nômôskar (নমস্কাৰ) is used. In Tamil, Namaste is known as Vanakkam (வணக்கம்) which is derived from the root word vanangu (வணங்கு) meaning to bow or to greet. In Malayalam, Namaskāram (നമസ്കാരം) is used.
