"Focus on your vocabulary first, then fix your grammar."

This is a maxim that has been drilled into my head over several years of my Spanish teachers saying this, but is there really any truth to this statement? Is there any scientific research proving that you can have a longer and deeper conversation with someone if you have a strong vocabulary and a weak grammar rather than if you had a strong grammar and weak vocabulary?

  • Studies is not a meta tag.

    @Flimzy I believe a tag that does not describe the content of the question is. We should require references in answers if the tag seems so favorable, not introduce a tag that's not about what the question is about. Ask this from yourselves: If I needed to find this question, will I include [studies] in my search? If a tag can't serve its primary purpose, it's a bad tag.

    @Flimzy Studies is easy to misread - there's already confusion between scientific-research, published-studies, studies, and learning-methods. We should figure this out.

    I've changed it to scientific-research rather than studies because I feel it accurately describes the question.
