I don't see why I think I can learn a foreign language. I can't even learn my native one correctly.
I've always thought that "towards" is correct, and "toward" is wrong. Until I was proof reading a short note, replaced the "toward" with "towards", and sent it back. When asked what's wrong with "toward", I replied that "toward" is wrong and one should always use "towards". "Really?" "Yes, really", so I brought out my Merriam-Webster English Usage as proof.
So imagine my horror to learn that both are equally correct.
And, even worse, "toward" is more common in American-English.
