kreisförmiger

Kreisförmiger is a German adjective meaning “circular” or “in the shape of a circle.” It describes objects whose outline or cross-section resembles a circle, for example eine kreisförmige Fläche (a circular area) or ein kreisförmiger See (a circular lake).

Etymology and formation: The word combines Kreis (“circle”) with the suffix -förmig (“-shaped”). This productive construction yields many shape descriptors in German, such as kreisförmig, blütenförmig, or würfelförmig. The related noun Kreisförmigkeit exists but is uncommon.

Usage and nuance: Kreisförmig is widely used in everyday language as well as in science, engineering, geography, and biology. It generally indicates a circular outline or cross-section, without guaranteeing mathematical exactness. If a perfect circle is intended, terms like kreisrund or genau kreisförmig may be preferred, depending on context.

Grammar and examples: Like other adjectives, kreisförmig inflects according to gender, number, and case. Examples: der kreisförmige Rand (the circular edge), die kreisförmige Fläche, das kreisförmige Loch, ein kreisförmiger See. Plural: die kreisförmigen Muster. After definite articles the endings are predictable; with no determiner the endings follow strong or mixed declension rules.
