Fester's right. Dropdown menus are the key elements of this software, if you're not sure how to conjugate a word but know the case, grammatica will show you the exact way it needs to be written in that case in the click of a mouse. No hassle. It also writes the translation of a word above it. And yes, it has neat grammar referece and dictionary. Only useful if you're writing in Russian a lot.

I was kinda trying to put several features in one screenshot so it came out a little messy....



Basically you can go to their website to see more. Just try the trial for 7 days
