orsó

Orsó is a Hungarian noun with several related but distinct meanings. In mechanical engineering and textile technology, an orsó is a spindle or cylindrical axis around which parts rotate. It is a key component in machines such as sewing machines, textile spindles, and fishing reels, where material is wound onto or guided by the spindle. The term can also denote a spool or reel used for winding thread, wire, or rope.

In anatomy, orsó appears in compound terms such as orsócsont, the radius bone of the forearm. While the plain word orsó is not typically used to name a bone in everyday speech, orsócsont refers to the spindle-shaped bone on the thumb side of the forearm. The word is used more broadly in various technical contexts to describe cylindrical or rotating components.

The usage of orsó is common in Hungarian technical, industrial, and medical language. Context usually clarifies whether the reference is to a mechanical spindle, a winding spool, or a anatomical term. See also orsócsont for the radius.
