The article describes Eugen Pauliny's theory of the origin of the Central Slovak rhythmic law. Pauliny's views on the rise of the rhythmic law involve the hypothesis that in Central Slovak, in contrast to Western and Eastern Slovak, the jers fell out or became vocalised before the vowel contraction occurred. A detailed historical linguistic analysis shows that this hypothesis has no basis in documented linguistic facts, and therefore neither has Pauliny's theory, which consequently cannot be considered plausible.
