Abstract
The article deals with the application of the concept of negative concord (Giannakidou, Hor-rocks, Denizot, Willmott), which is not reflected in standard reference books on Ancient Greek (including the most recent books by Basile and Crespo) and is not used in Czech Hellenistic circles. Taking into account the well-known rule of the accumulation of negatives of the same kind (οὐ ... οὐδεις, οὐδεις ... οὐ), the author offers support for certain surprising yet convincing findings by Denizot concerning the sequence of οὐδεις ... οὐ and argues that Ancient Greek is a non-strict negative concord language.
