jäse

jäse is a native Estonian noun meaning limb or appendage. It denotes a major projecting part of an animal or human body that is used for movement, manipulation, or interaction with the environment. In everyday Estonian, more specific terms such as käsi (arm/hand) and jalg (leg) are commonly used, while jäse serves as a broader, more technical designation that can refer to any limb or analogous appendage across species, including wings, fins, or antennae in some contexts.

In medical, veterinary, and biological texts, jäse is used to discuss topics such as the structure, function, injury, or rehabilitation of limbs, as well as comparative anatomy across different organisms. The word appears in anatomical dictionaries and scientific literature written in Estonian, often in compound forms that specify the type of limb in a given context.

Etymology: jäse is a native Estonian word. Its precise historical development is not widely detailed in English-language sources, but it is part of the standard Finnic lexicon related to limb-type concepts.
