nachzubessern

Nachzubessern is a German verb meaning to improve or rectify something after it has already been delivered, evaluated, or initially completed. The prefix nach- conveys a follow-up action, so the term emphasizes corrections or refinements made subsequently rather than at the first attempt. The expression is common in everyday language as well as in business and legal contexts, particularly regarding products, services, or contracts that require further adjustments.

In grammar, nachbessern is a separable prefix verb. In finite forms the prefix is separated in main clauses, for example: Ich bessere den Fehler nach. The past participle is nachgebessert, and the infinitive form used with modal verbs or in dependent clauses is nachzubessern. The noun form das Nachbessern (or more commonly die Nachbesserung) refers to the act of making corrections.

Usage and contexts include consumer protection and warranty matters, where a seller or service provider is obliged to perform post-delivery corrections as part of Nacherfüllung. It is also used in manufacturing, software development, and service sectors to describe iterative fixes or improvements implemented after initial delivery.

Examples:

- Der Hersteller muss die mangelhaften Bauteile nachbessern.

- Die Software soll in der nächsten Version nachgebessert werden.

- Wir werden das Produkt nachbessern, um die Funktionen zu verbessern.

Synonyms and related terms include nacharbeiten, korrigieren und verbessern; in rechtlichen Kontexten wird oft von Nacherfüllung gesprochen, wozu Nachbesserung eine gängige Form der Abhilfe ist.

In sum, nachzubessern denotes post-delivery corrections aimed at achieving a better or proper state after initial issues have been identified.
