Potwierdzeniu is the locative and dative singular form of the Polish noun potwierdzenie, which means confirmation, attestation, or proof. The term can refer to a statement or document that confirms a fact, a validation of information, or the act of confirming something.

As a neuter noun, potwierdzenie has several inflected forms. The base form is potwierdzenie. In standard declension, the genitive is potwierdzenia, while the dative and locative singular share the form potwierdzeniu, and the accusative remains potwierdzenie. The instrumental singular is potwierdzeniem. These variations determine how the word appears after different prepositions and in different syntactic roles.

Potwierdzenie is widely used in legal, administrative, financial, and everyday contexts. It can denote a formal certificate or document that proves an event or condition, such as potwierdzenie zapłaty (proof of payment) or potwierdzenie odbioru (acknowledgment of receipt). It also appears in phrases like potwierdzenie faktu (confirmation of a fact) or potwierdzenie danych (verification of data). In many situations, the concept emphasizes validation or corroboration provided by an authority, institution, or official record.

Etymology traces potwierdzenie to the verb potwierdzić, meaning to confirm, from the prefix po- combined with twierdzić, to claim or assert, and the nominalizing suffix -enie. Related terms include potwierdzać (to confirm) and potwierdzenie itself as the general concept of confirmation or verification.
