Tulwar ... or talwar

[fernando]

Thanks for the answers.
I see the point, but i didn't put it the right way.
Forget the spelling. What i am actualy puzzled with, is the sounding.
Now, if i well understand Ariel, the w sounds like v
Still they ought to sound either tulvar or talvar.
Or do they sound something in between ?
Maybe in english terms this looks more like a false case, but in Portuguese u and a have very distinct sounds, and there should be no ambiguity.
Do i make any sense ?
