The Gemara discusses whether we can learn anything from the vov in the posuk ending with v'nitmaah. (and she became t'maya.) It's a machlokes. It seems to me that the vov in v'nitmaah is a vov hachibur, an attaching vov serving the function of "and" in English. If the posuk didn't have that vov the Torah would not be using a valid, grammatical Hebrew sentence. The sentence structure would be all off. The Torah always uses grammatically connected sentences. In fact the Torah is the source of all Hebrew, ancient and modern. I don't really see how the mon d'amar who holds the vov is extra would have us read that posuk without the vov.
