zyklische

Zyklische is a German adjective meaning cyclic or related to cycles. It derives from the noun Zyklus (cycle) and the native adjective suffix -isch, with its roots in the Greek kyklos. The form zyklische is used before a noun in singular when a definite determiner marks the case and number (for example die zyklische Gruppe, das zyklische System, der zyklische Prozess) and follows the standard German adjective endings for definite articles. The related noun Zyklus is common in scientific and everyday language, and zyklisch functions as the adverbial form.

In science and scholarship, the term appears across disciplines to describe repetitive or ring-shaped structures and processes. In mathematics, zyklische Gruppe denotes a cyclic group generated by a single element; in graph theory one may encounter zyklische Graphen for graphs containing cycles. In chemistry, zyklische Verbindungen refers to compounds with ring structures, including zyklische Aromaten for cyclic aromatic compounds. In economics, zyklische Schwankungen describe business cycles, and zyklische Branchen refer to sectors sensitive to economic fluctuations. The word also appears in geology, ecology, and physics to characterize periodic, repeating, or ring-like phenomena.

Grammatical notes: zyklische behaves as a typical attributive adjective after a definite determiner. Its endings adapt to case, number, and gender (die zyklische Gruppe, des zyklischen Systems, den zyklischen Graphen, die zyklischen Gruppen). The adverbial form is zyklisch. Related terms include Zyklus, zyklisch, and zyklische Graphen as examples of its multidisciplinary usage. See also Zyklus and zyklisch for related concepts.
