Ciągłość rozwoju języka polskiego

In the description of the evolution of the Polish language, there are two basic categories: the sequence of historical events and the sequence of language changes. Both of these categories determine the category of continuity as the basis for evolutionary changes. The mobility (power) of a language depends on intra-lingual and extra-lingual factors the infl uence of which enables the implementation of the basic sociolinguistic functions of that language on the systemic and textual planes. Sources provide evidence for language development continuity, which is realised in forms of public discourse and the assigned speech registers and communication-stylistic variants. The entirety of the processes determining language development continuity follows the trend of optimising it as a form of communication of a certain communication community.
