ENAuthor of the article hopes to demonstrate that reorganisations we occasionally observe in inflectional patterns of natural languages are caused not by universal properties of human cognition but rather by structural influence of other inflectional patterns. In most cases, these model patterns can be identified within the grammar of the language in question. However, in several securely established cases a suitable model can be found only in the linguistic neighbourhood of a language. The concept of contact-induced reanalysis in inflectional patterns has the potential to satisfactorily resolve several old problems in the historical morphology of Bailtic languages.
