Hi 😀 welcome to our family, I don't speak Russian but I speak up to 7 languages so I can give you some useful tips. Yes, unfortunately we don't have a grammar overview course for Russian yet but we are planning to add lots of new content for Russian in January.
For the time being I suggest you to not focus too much on the grammar but to assimilate the language through practice. Yet try to have some reference to check conjugations, cases and these little things. I'm also going to provide you a link to a website where you can check translations much more quickly and effectively. https://context.reverso.net/ . Russian grammar is not easy as far as I know, therefore focusing too much on it won't work so well.
We are really happy to see you appreciate our website and we'll always do our best to provide you with how much support as possible.
Thank you for your kind and helpful tips. I appreciate it so much. I'll check it out. Have a nice day!
Hi Mehmet, as Davi said unfortunately we do not have anything regarding Russian grammar at the moment ☹️
We work on a new Russian course, but it will consist mainly very simple short stories.
In the meantime, if you have a specific question about Russian grammar, please post it in Questions section. I will ask some Russian friends to answer it.
