A history of Polish in speech and writing, following inherited sound patterns, contact, alphabets, manuscripts, print, codification and changing communities. West Slavic: Polish develops through Lechitic traditions with a Latin-based writing system and extensive multilingual contact. Geographical scope: Poland and selected scholarly, publishing and language-policy developments.
This researched selection contains 17 dated moments and 3 explanatory cards. Use aspect tags to compare pronunciation, writing and spelling, grammar and contact, standardization, evidence and social varieties. Connected moments identify related documents or developments; a line alone is not a claim of direct causation or an inevitable progression toward a national standard.
Reading sound history
/Slashes/ mark phonemic analysis; [brackets] mark phonetic realization; an asterisk marks reconstructed forms. Examples identify a historical stage or variety and should not be imposed on every speaker. Ancient and medieval pronunciation is reconstructed from spelling, metre, comparative evidence and contemporary descriptions. It is not an ancient sound recording. Modern recordings and corpora supply different evidence.
Sound changes spread through words, communities and generations. Approximate year anchors locate a broad process; they are not exact birthdays. Work composition, surviving manuscript copying, printing, fieldwork, legislation and later research publication have different dates. A language did not begin when its first surviving document was written.
Writing, institutions and variation
Standard spelling and prestige pronunciation have social histories. A policy or dictionary does not instantly make every person write or speak alike, and borrowed vocabulary does not alone change a language’s ancestry. Regional and overseas developments, multilingual contact and contested norms are identified where relevant. This survey does not claim to represent every community or every sound change.
All coordinates use Gregorian CE/BCE; coarse dates do not assert an exact first day. There are no duration bands ending at the creation date. Ongoing varieties and long linguistic eras are represented by dated evidence and qualified moments.
Each entry includes supporting sources, with emphasis on original documents, manuscript and book catalogues, scholarly research, language institutions and corpus archives. Institutional prescriptions are treated as evidence of a proposed norm, not proof that competing everyday varieties are defective.

c.1440 · Parkoszowic proposes a systematic Polish orthography
language: polish
aspect: writing and spelling
Jakub Parkoszowic’s treatise addresses the difficulty of representing Polish sounds with Latin letters. His proposals reveal an early explicit analysis of sound distinctions and graphic alternatives. The scheme is an intervention, not evidence that all scribes adopt the same conventions. Its approximate dating belongs to manuscript and intellectual history, while the pronunciation distinctions it attempts to represent have earlier histories. **Cross-timeline connection:** The University of Warsaw study identifies connections between Parkosz’s programme and the earlier Czech reform associated with Hus, while also explaining his avoidance of some proposed devices. Similarity and differences both matter. **Date and evidence:** 1440 CE. approximate manuscript-treatise date. Gregorian CE/BCE. Year and month coordinates use the first day only for placement. A representative anchor for a gradual linguistic process is not its exact beginning; manuscript, composition, publication and policy dates are distinguished. **Sources:** - [University of Warsaw: Parkoszowic’s orthographic treatise](https://gramatyki.uw.edu.pl/book/3)
