What does good afternoon mean in sanskrit language?

There's no direct equivalent for "good afternoon" in Sanskrit, as the language doesn't have a specific greeting for that time of day.

However, you could use these options:

* सुप्रभातम् (Suprabhātam): This literally translates to "good morning," but it's often used in a broader sense for any time before evening.

* शुभं दिवसम् (Shubham Divasam): This means "good day," and it's suitable for any time during the day.

* शुभं संध्याकालम् (Shubham Sandhyākālam): This literally means "good evening," but you could use it for the late afternoon if you wanted a more formal or poetic greeting.

Ultimately, the best choice depends on the context and formality of your greeting.
