Hi Mike!
I agree with Tdol. Even though we can technically distinguish various language skills, there's not much sense in favouring one at the expence of others. I just don't quite get it why it seems so attractive to confront whatever it is - vocabulary, pronunciation, discourse, etc. - with grammar. I can't think of any example of 'good' pronunciation without good grammar? What's it like - random words?
As a teacher, I could see your point (I think) and as a big fan of phonology, I am trying to teach grammar (and vocabulary) through pronunciation. As a learner, I'd definitely go for a reasonable mixture of everything.
It would be nice if you could share your experience.
Hey Esgaleth!
I actually just wanted to know whether good grammar is more important than GOOD pronunciation.

Often poor pronunciation leads to misunderstandings.
