nachträglicher

Nachträglicher is a German adjective meaning belated, retrospective, or occurring after the fact. It is used to describe something that affects or relates to a past event or situation, often implying that an action or change is applied later than initially planned or expected. The word can express a sense of later addition, revision, or compensation.

Grammatically, nachträglicher is the attributive form of nachträglich for masculine singular nouns in the nominative or accusative case. It declines like other German adjectives: der nachträgliche Schaden, einen nachträglichen Anspruch, ein nachträgliches Datum. For feminine nouns, the form is nachträgliche (die nachträgliche Genehmigung), for neuter nouns nachträgliches (das nachträgliche Datum), and in plural it is nachträgliche (die nachträglichen Änderungen). The adverbial form is nachträglich, as in etwas wurde nachträglich korrigiert.

Common usages include legal, administrative, and contractual contexts, where after-the-fact actions are described. Typical collocations are nachträgliche Änderung, nachträgliche Genehmigung, nachträglicher Anspruch, or nachträgliche Anpassung. In legal language, the term is often contrasted with rückwirkend, which more explicitly denotes retroactive effect in law; nachträglich is broader and frequently used in everyday and formal settings.

Examples:

- Der nachträgliche Anspruch auf Erstattung wurde anerkannt. (The belated claim for reimbursement was recognized.)

- Eine nachträgliche Änderung des Vertrags war notwendig. (A subsequent modification of the contract was necessary.)

- Das Datum wurde nachträglich angepasst. (The date was adjusted retroactively.)
