Reparierenden

Reparierenden is the present participle form of the German verb reparieren, meaning to repair. In German grammar it functions mainly as an adjective or as part of a participial phrase describing an ongoing repair action. As an attributive adjective it agrees with the noun it modifies in gender, number, and case, often taking the ending -en in many cases such as after definite articles or in certain declensions. For example: Der reparierende Techniker arbeitet an der Maschine.

The form reparierenden appears across cases and genders when declining the participle as an adjective. Common examples include den reparierenden Techniker (accusative singular masculine) and dem reparierenden Techniker (dative singular masculine). In feminine or plural forms the endings change according to standard German adjective declension, for instance die reparierende Technikerin (nominative singular feminine) or die reparierenden Techniker (nominative plural).

In addition to its adjectival use, the verbal noun das Reparieren denotes the act or process of repairing. This noun form is used to refer to repair work in a general sense or when discussing procedures, policies, or standards related to maintenance and restoration. The verb reparieren itself is of German origin and is built with the common -ieren suffix used to form verbs from borrowings or native roots.
