Hi there - will i learn grammar and how to use words etc.
You may have to consult external sources to provide some background to the grammar, or you can ask specific questions here on the tutor forum. Mostly, however, you will become familiar with the patterns of the language through lots of listening and reading and LingQing. Stay the course!
As Steve said, you will begin to notice patterns within the language the more familiar you get as you use LingQ more and more. However, if you still want a proper explanation of things, and you’ve already asked a tutor, there are many websites to explain the grammar, and there are many books you can get that focus specifically on the grammar.
