A very unpredictable ‘person’: A corpus-based approach to suppletion in West Polesian

In Slavic languages, as in many other languages, the noun for person has a suppletive paradigm. Yet, as this study shows, in West Polesian (East Slavic) the noun person is a typological outlier not only within Slavic but also cross-linguistically because it combines three stems with a very complex distribution. This paper looks for any regularities in the distribution of these suppletive stems, their cognates among other Slavic languages and how speakers use them in free texts. This survey provides novel insights into suppletion. First, suppletion involving more than two stems is typologically uncommon but the West Polesian noun person combines three. Second, against any expectation of regularity for the sake of learnability, free-text data show that speakers do not distribute the stems homogeneously. Third, notwithstanding the diglossic situation in Western Polesie, the inter- and intra-speaker variation in the choice of stem does not seem particularly conditioned by sociolinguistic variables such as gender, age or social class. In sum, this corpus survey of the suppletive stems of person in West Polesian and Slavic illustrates a rare case in morphological typology where there is a three-stem suppletion combined with overabundance and a vast amount of variation across speakers.
