How do you write the word hello in Hindi?

There are a few ways to say "hello" in Hindi, depending on the context and formality:

Formal:

* नमस्ते (namaste): This is the most common and polite greeting. It's a respectful way to say hello, similar to "good morning" or "good evening."

* शुभ प्रभात (shubh prabhat): This translates to "good morning" and is used in the morning.

* शुभ संध्या (shubh sandhya): This translates to "good evening" and is used in the evening.

Informal:

* नमस्कार (namaskaar): A slightly less formal version of "namaste."

* काय हाल आहे? (kay haal aahe?): This translates to "how are you?" and is a friendly way to greet someone.

* क्या हाल है? (kya haal hai?): This is the Hindi version of "how are you?"

* हाय (hai): This is the English word "hi" and is commonly used in informal settings.

The best way to choose which greeting to use depends on the situation. If you're unsure, "namaste" is always a safe choice.
