नमस्ते (namaste)

interjection A single-sense word: the standard Hindi greeting/farewell used at any time of day, to anyone.
Sense 1 : greeting/farewell
interjection
Synonyms: नमस्कार (namaskaar, slightly more formal), नमस्ते जी (namaste jii, with added respect)
Frequency: high
Cultural Note: नमस्ते (namaste) literally comes from नमः (namah, 'bow/salutation') plus ते (te, 'to you'), so at its root it means 'I bow to you' -- Hindus often say it while pressing the palms together at chest height, a small gesture worth mimicking. It is the safe, universal choice regardless of who you are speaking to -- elder, child, stranger, boss -- unlike English 'hi' versus 'good morning,' Hindi does not force you to think about time of day.
Common Mistakes: 1) Learners often reach for अलविदा (alvidaa) to say goodbye, but नमस्ते (namaste) works fine for both hello and goodbye -- अलविदा (alvidaa) sounds oddly final, almost like 'farewell forever,' and is rarely used in everyday partings. 2) Because it is grammatically frozen, learners sometimes try to conjugate or modify it (adding tense markers, etc.) -- it never changes form, in any context, to anyone.
