is based on the usage
The polish language is highly inflected. In that respect, it is extremely similar to German and Latin. It is also like Latin in that it has no articles: You cannot say "the foo", only "foo". You can say "a foo" by saying "one foo", however.
All nouns, pronouns, and adjectives are inflected by both case and gender, to agree with the noun in the clause.
