We just learned some greetings in Hindi, like नमस्ते (namaste) and अलविदा (alavida) and शुभ प्रभात (shubh prabhaat), नमस्कार (namaskaar), सुसंध्या (susandhya), शुभ रात्रि (shubh raatri).
To say How are you? in Hindi you would say:
आप कैसे हैं? (aap kaise hain?) - sounds like ah-p kay-see hay-in 文A
To respond and say Very good thanks, you would say:
बहुत अच्छा धन्यवाद। (bahut achchha dhanyavaad) - sounds like bah-hut ah-chah dah-n-yay-vah-d 文A
