Oh, there's something I wanted to ask.
Could someone give me a "general rule" about how to form sentences in Japanese?
I already know about the Subject-Object-Verb style of japanese language, but if I want to say "I'm studying japanese". I suppose it is "Nihongo benkyousuru", not sure. But if this is correct, there are no particles? And where should I use the "desu"? I know it's used at the end of some sentences, but when exactly?

I basically want to be able to discover the meaning of any word and create a sentence with it. For example, I want to be able do find out how "japanese" and "study" is in japanese, and know how to create sentences with them.

Thanks a lot =]
