Book excerpt: The latest volume of OLINCO proceedings is a selected set of sixteen papers that grew from presentations at OLINCO 2023 - the international Olomouc Linguistics Colloquium held at Palacký University in June 2021. The papers collected here are unified by the topic of the colloquium: Language Use and Linguistic Structure, in that they all, in one way or the other, address the central questions of the study of human language. They all use standard scientific methodology and theory and solidly researched empirical evidence in favor of formalized structural representations of the language system.
