Polish Adjective cases
Similar to English, Polish adjectives, nouns usually precede their nouns; however, their forms change to respect their nouns.
Polish adjectives agree in gender, number and case with their respective nouns. For example if the noun is singular, then the adjective will agree with the noun in gender, that is masculine, feminine or neuters, number (singular), and case.
Remember that masculine nouns, have two forms, that is animate, referring to people and animals, and inanimate.
As with noun cases adjectives are a matter of learning the endings and practice.
