They're not that far removed concepts, though -- hard to do one without doing the other, at the least.
It's the same in Swedish ... and maybe also Turkish, but my brain is a bit scrambled.
"I'm studying.". "I am studying." or "I study." although I haven't tested all three yet. Then also "I'm reading.", "I am reading." or "I read." so there could be six altogether, but I don't know if the contractions are accepted.
