lithen
Lithen is a term used to describe something that is supple, flexible, and graceful in movement. It often suggests a quality of ease and fluidity, as opposed to stiffness or awkwardness. This characteristic can be applied to a variety of subjects, from the physical attributes of a person or animal to the style of an artistic performance or the movement of an object.
For example, a dancer might be described as lithe if they move with elegant and effortless precision.
