Supporting data for: Ukrainian Indefinite Pronouns and Language Typology

<b>Dataset abstract:</b> In order to shed light on the distribution of Ukrainian indefinite pronouns and adverbs we carried out corpus searches and created datasets with corpus data which were subjected to empirical analysis. Ukrainian indefinite pronouns and adverbs consist of two parts, viz. an interrogative (question word, e.g. що ‘what’) and an indefiniteness marker. The datasets are organized in a way that enables us to investigate the frequency and meaning of the attested combinations of interrogatives and indefiniteness markers. We carried out corpus searches and exported the data to a spreadsheet, where additional annotation was added.
