Nelétajících

Nelétajících is a Czech adjective that translates to "non-flying" or "flightless." It is used to describe creatures or objects that are incapable of flight. The most common usage of nelétajících is in the context of birds. While the vast majority of bird species can fly, there are several notable exceptions, such as ostriches, emus, kiwis, and penguins. These birds are described as nelétajících.

Beyond the realm of birds, the term can also be applied to other organisms that have lost the ability to fly over evolutionary time, or to insects that are naturally wingless. For example, certain species of ants or fleas are nelétajících. In a more abstract sense, it can also refer to things that are designed without the capacity for flight, or that have had their flight capabilities removed. The term emphasizes the absence of aerial locomotion.
