The article will attempt to verify the hypothesis stating that, in contemporary Polish (especially in colloquial language), syntactic structures containing two imperative verb forms may be defined as serial verb constructions (SVCs). As our starting point, we assume that structures such as idź głoś, idź się utop (lit. resp. ‘go preach’, ‘go drown’) which are the subject of our analysis, fall into the definition of SVC containing five components: compositionality, being monoclausal, the two verbs being independent and having no linking element and no predicate-argument relation between them. In the analysis that follows, we will concentrate on structures containing the element idź (‘go’) and discuss their characteristic features concerning prosody, morphology (mode and number adjustments), semantics and syntax. We consider those characteristics as non-standard, i.e. specific for those types of serial verb constructions.
