Formal:
* शुभ दोपहर (Shubh Dopahar) - This is the most common and formal way to say "good afternoon."
Informal:
* नमस्ते (Namaste) - This is a general greeting used throughout the day, but it can also be used as a more casual way to say "good afternoon."
Other options:
* अच्छी दोपहर (Achchhi Dopahar) - This translates directly to "good afternoon" and is a more colloquial way to say it.
* दोपहरिया (Dopahariya) - This is a shorter and more casual way to say "afternoon."
The best way to choose the right phrase is to consider the context. For example, you would use "शुभ दोपहर" when speaking to a teacher, boss, or someone you don't know very well. You could use "नमस्ते" or "अच्छी दोपहर" with friends and family.
