We really really need better hover hints or better grammar explanations, because it is not useful to learn phrases and not why they are formed that way. I'm getting really really tired of trying to sort out what you mean. It's getting to the point where I may have to buy a Russian grammar book to work through a Russian language course.
My instructor provided us with a Russian grammar table; if I ever find it again, I'll find a way to upload it. It was incredibly helpful on this point. And once you get a feel for them, they aren't as challenging as they first seem. You can google them as well though. For verbs it's pretty similar to Spanish. The ending of the verb is dependent on who is doing the action. I, you, he, they, all have different conjugations.
That's what the comment section is for! :) besides, you can always google it. That's what I do. There are a lot of helpful grammar sites out there for popular languages such as Russian. That said, I know what you mean.. I've had trouble with that before, and not just in Russian. xD That's why I know this.
Yes, you could put "здесь" at the end, but it conveys a slightly different meaning. Actually, the Tips Notes section for this group of lessons (Basics 1) advises the following:
"Unlike English, adverbs are NOT universally grouped at the end. "
That said, olimo, in another post, had this to say about the topic:
The word order is not strict, but different orders have different meanings or emphases:
•Мама там = Mom is there - very neutral, without any emphasis, answers the question "where is Mom?"
•Там мама = Mom is there / It is Mom who is there - "mom" is emphasized as opposed to someone else, this sentence answers the question "Who is there?" [Can also mean "There she is!"]
Probably the single most important point to take from all of this (if you remember nothing else) is this: Typically, the adverb comes before the verb in Russian.
Even in English, writers are taught to place the most important word or words at the end of a sentence to highlight them/make them more prominent. For one example, visit the web page "PLACE IMPORTANT WORDS AT THE END OF THE SENTENCE". It is one of many pages/web sites that advise writers to do this.
Hope that helped.
