This paper describes Hungarian infinitive constructions using a data-driven approach.It aims to study these constructions along formal-distributional features, utilizing authentic corpus data and frequency counts.Our findings derive from an open-source dataset extracted from a 776.9-million-word treebank of Hungarian.The resource contains more than 9 million instances of infinitive constructions, annotated for a wide range of linguistic features and metadata.We discuss the following topics: inflected infinitives, verb clusters consisting of multiple infinitives, auxiliarylike lexical items, separable preverbs, the attested word orders of infinitives, finite verbs and their respective preverbs, and finally, detailed distributions of preverbs in infinitive constructions.Our study reveals some trends which would have remained unseen without a quantitative approach.
