Kateryna Krykoniuk

Research student,


My main research interests concern morphology (both derivational and inflectional) and syntax. These areas are equally important in our understanding of how different grammatical functions are realized in various languages.

I was awarded a BS in Oriental Studies and MPhil Philology with Distinction by the National Shevchenko University of Kyiv (Ukraine) in 2001 and 2003 respectively. In 2015, I completed my PhD, “Formal Morphology of Persian Innate Word Formation”, from Krymskyi Institute of Oriental Studies in Kyiv (Ukraine).

Currently, I am doing doctoral research in the School of English, Communication and Philosophy, entitled “Morphological regularities and patterns in English word formation”. In this research, I am exploring mechanisms that govern the arrangement of morphemes in the lexicon of English using formal morphological approach and statistical methods. The aim of the study is to develop an optimal description of word formation processes in modern English by building a morphological meta-corpus.

I was awarded the Houtan Foundation Scholarship in 2018 and 2019.

Current projects

Morphological regularities and patterns in English word formation. As part of my current PhD research, I am developing a morphological meta-corpus that allows us to create a general picture of word formation processes in English. Questions I investigate include: what are the morphological regularities and patterns that govern the organization of morphemes in word formation processes? What do these morphological regularities reveal about the grammatical resources of English? How does the meaning of morphemes correlate with their form? What is the role of type frequency, morphological type valency and productivity in word formation grammars? Finally, how word formation processes in English differ from that in other languages?

Approximate Entropy of word order in spoken and written Persian. The aim of this study is to explore the possible variations of subject-object-verb patterning in present-day written and spoken Persian. This is done by exploring 1000 sentences in total, taken equally from two sources: an academic book and the Corpus of Conversational Persian (Mohammadi 2019) as representative of spoken Persian. After encoding the linguistic units of interest manually, the value of randomness in two sequences of patterns—one representing the written language and the other spoken—is quantified using the method of approximate entropy (ApEn) developed by Pincus (1991) which allows us to pinpoint changing complexity from a relatively small amount of data.
