What is seva main in informal Hindi letter writing?

"Seva mein" is a formal Hindi phrase meaning "To the service of". It is used in formal letters to address the recipient.

In informal letter writing, you wouldn't use "Seva mein" directly. Instead, you would use something like:

* "Pyaare/Pyaari..." (Dear...) followed by the name of the recipient.

* "Aapko..." (To you...)

* "Namaste..." (Greetings...)

Here are some examples:

* Formal: Seva mein, Shri. Sharma Ji

* Informal: Pyaare Sharma Ji

* Formal: Seva mein, Mahila Samaj

* Informal: Aapko, Mahila Samaj

The choice of greeting depends on your relationship with the recipient and the tone of the letter. Remember, informal letters are more relaxed and casual.
