As ravi sir mail means in telugu

A common question!

"Ravi Sir" is a common way to address a person named Ravi who is considered to be a respected or senior individual, often in a professional or academic setting. In Telugu, this can be translated to:

• "రవి గారు" (Ravi Gaaru) - This is a more formal way of addressing Ravi, with "Gaaru" being a respectful suffix used to show respect or deference.
• "రవి సర్" (Ravi Sir) - This is a more informal way of addressing Ravi, with "Sir" being a common title used to show respect or authority.

So, if someone says "Ravi Sir", they are essentially saying "Hello, respected Ravi" or "Hello, senior Ravi".
