A Note on GA
There is a lot of similarity between WA and GA, in that they both
have to do with the subject of the sentence. However, here is a
way to keep them straight.
GA - "This, as opposed to something else"

[Ranma sj here at exists.]
Ranma is here.
ranma wa koko ni iru.
[Ranma topic here at exists.]
Ranma is here. (this may or may not indicate emphasis on here
Similar? Yes. However, they would answer different questions. If
someone said, "Where is Ranma?" you would respond "Ranma
is here." On the other hand, if someone said, "Who is in here?"
someone might respond "RANMA is here".
