Wiederkehrender

Wiederkehrender is a German adjective meaning recurring or returning, used to describe something that happens again or reappears over time. It is derived from wiederkehrend, which itself comes from wieder- (again) and kehren (to return or turn).

In everyday language, wiederkehrender appears in various inflected forms depending on gender, number, and case. The base form often seen in writing is wiederkehrende (attributive form), as in eine wiederkehrende Erscheinung or ein wiederkehrendes Muster. The form wiederkehrender occurs in specific grammatical positions, for example dem wiederkehrenden Muster (dative) or des wiederkehrenden Musters (genitive). This pattern reflects regular German adjective declension after definite or determiner phrases.

Wiederkehrender is commonly used across several contexts to convey recurrence or periodicity. It can describe cycles in nature, repeated events, or patterns in data. In scientific or technical writing, it often appears alongside terms like Muster (pattern), Ereignis (event), or Phänomen (phenomenon) to indicate that something tends to reoccur. In medical contexts, similar terms such as rezidivierend or rekurrent are used for recurring conditions or symptoms, but wiederkehrender can still be found in general prose.

Examples:

- Eine wiederkehrende Erscheinung tritt im Frühling auf.

- Das wiederkehrende Muster in den Daten deutet auf eine zugrunde liegende Regelmäßigkeit hin.

- Dem wiederkehrenden Fehler muss nachgegangen werden.

Wiederkehrender thus functions as a flexible, everyday descriptor for recurrence, with its exact form varying to fit standard German adjective endings.
