kulová

Kulové is the neuter singular form of the Czech adjective kulový, meaning spherical or ball-shaped. It is used to describe objects that have the form or characteristics of a sphere and is derived from the noun koule (sphere, ball).

Etymology and usage

In Czech, kulové is typically part of a compound noun or noun phrase, where it agrees in gender and number with the modified noun. It is not a standalone noun; rather, it functions as an attribute to describe the shape of an object.
