A brief history:
The Polish language of today (referred to as “modern Polish”) dates back to the 1930s. The language became much more homogeneous during the 20th century due to mass movements of people within Poland. But the language naturally has a much longer history: the first Slavs arrived in Central Europe in the Middle Ages and the East Slavic languages group began to develop. The Latin alphabet was adopted when the Polish State was created in the 10th century but the first Polish dictionary wasn’t published until the 19th century.
Polish has three genders (masculine, feminine, neuter) and seven cases (nominative, genitive, dative, accusative, vocative, instrumental and locative).
