What is the meaning of ambassador in hindi?

The most common word for ambassador is राजदूत (Rajdoot). This is an important person from one country who works in another country. For example, the Rajdoot of India in my country, France. He is the main representative.

You can also hear the word दूत (Doot). This is a more general word. It means envoy or messenger. So it is a little different. Another word is सफ़ीर (Safir). This word is very formal, you maybe hear it on the news. In my language, French, we say 'ambassadeur'. The word 'Safir' sounds a little bit similar to me.

So, for most times, राजदूत (Rajdoot) is the best and correct word. I hope this is a help for you.
