Polish Genitive Case (Dopełniacz) Explained

The Polish genitive case, known as dopełniacz, is used to answer the questions “kogo?” (whom) and “czego?” (what). It marks relationships of lack, possession, quantity, part‑of‑a‑whole, and is triggered by specific prepositions (e.g., bez, po, podczas), certain verbs (e.g., szukać, potrzebować, bać się), and negation, where the accusative often shifts to the genitive.

Typical examples include “szukam kolegi – kogo?” (I am looking for a colleague), “potrzebuję wody – czego?” (I need water), and “brakuje cukru – czego?” (Sugar is missing). The case also appears after numerals and quantifiers such as dużo, mało, kilka. Recognising the genitive involves asking the question from the verb or predicate, which helps distinguish it from the accusative.

Understanding these patterns aids correct sentence construction in everyday Polish and more complex texts.
