abgerundeten

Abgerundeten is a declined form of the German adjective derived from the past participle abgerundet, meaning rounded off or having rounded edges. It is used to describe objects whose edges or corners have been shaped with a radius, smoothing sharp transitions.

Origin and grammar: the word comes from ab- (prefix meaning away or apart) and runden (to round). The participle abgerundet functions as an adjective in noun phrases, and its endings follow German adjective declension rules. The form abgerundeten is typical in plural contexts after a definite determiner, for example die abgerundeten Ecken or den abgerundeten Ecken, as well as in certain mixed or weak inflections. In the singular, you may encounter abgerundete Ecke (nominative/accusative) or der abgerundeten Ecke (dative/genitive forms vary by case).

Usage and contexts: abgerundeten is common in geometry, product design, architecture, and manufacturing, as well as in digital interfaces. It describes shapes with safety or aesthetic advantages. Examples include abgerundeten Kanten (rounded edges) on a metal lid, abgerundeten Ecken des Gehäuses (rounded corners of the case), or abgerundeten Schaltflächen in a software interface (rounded buttons). The predicate form is often expressed as es ist abgerundet or die Kanten sind abgerundet.

Notes on variation: without a definite article, the attributive form becomes abgerundete Ecke or abgerundete Kanten, depending on number and gender. The term is largely synonymous with filleted in technical contexts and is widely understood in design and engineering German.
