There are actually two lists of languages. One for manually tagging which language you are using here on Connect And the other one is the list of languages available for automatic translations. The second one is the important one. I believe Google Translate is capable of translation to and from the languages you mentioned, @Rakshi2 .
If not, please make the necessary requests in the Google Translate help forum.
By the way having a language on the manual tagging list has no influence on the translations.
You are right, the languages mentioned by you are not actually available in the Language Settings in Connect, so in fact it is not possible to have the whole site in your language. New Languages are added time by time, and the Indian Community is very large, so I am tagging @DeniGu to escalate your request to the team.
Actually you can read a post in your language using the translator embedded in Connect, as mentioned by @MortenCopenhagen and @SholaIB , and of course feel free to write a post in the language you like more.
Have a nice evening
EDIT: Of course the selection of the language in Settings will only impact the menu and the commands
I am not going in deeply in conversation, but in my experience when I wrote on connect in my religion language ( Marathi ) I usually write on Notepad of my mobile then I copy paste in connect and then edit and then post…
There are currently no plans to add more languages to the languages available in your Settings on Connect.
As @ErmesT mentioned, the language list in Settings impacts the translation of the different sections on Connect. You can still read all posts in your preferred language by selecting it from the Google Translate drop-down menu. This menu is available in the top right corner of every post page. You can see @SholaIB 's helpful screenshots for reference.
I’ll mark my comment as the solution to this post so it’s more visible to other Local Guides who might have similar requests and questions. If our plans change, I’ll update my comment as well. Thank you all.
