Abstract
The paper examines interjections and their position in the Czech language system, focusing on their definition and classification. We first concentrate on problematic transitions between interjections and paralinguistic cues (sounds) and then on the definition of interjections from three basic perspectives - morphological, syntactic and semantic.
We review the concept of interjections in some Czech grammars and provide commentary and critical remarks regarding it. We conclude with the proposal of an all-embracing definition and a new classification of interjections.
