Periodisations of history are usually presented in synthesising studies. Analysis of the hitherto periodisations of the history of the Polish language enables compilation of a summary proposition, which includes also the recent history of Polish (since 1939). Its internal periodisation is based on the following criteria: 1) record of qualitative intra-linguistic changes; 2) hierarchy of intralinguistic development trends of the system of the Polish language; 3) system of sociolinguistic trends; 4) infl uences of extra-linguistic and non-linguistic processes.
