I edited that a bit, having been inspired by an article by one Czech linguist from Charles University who did some research on interdialects in the Czech Republic. It is untrue that the Moravians speak "correct" Czech. There is no thing as "correct" Czech. Moravians have more forms that resemble "standard" Czech (or literary language), but it does not mean they speak "correct" Czech, because on the other hand, they have MANY forms that are totally out of standard (especially in the vocabulary field).
