the word 'unbending' is a straightforward english compound formed from native germanic elements. its core, 'bend,' originates from the old english verb bendan, which initially meant "to bind" or "to constrain with a string," particularly in the context of a bow for shooting. the present participle suffix '-ing' was added to create an adjective meaning "that which bends." the prefix 'un-', the most common english negator from old english, was then attached to reverse the meaning. the literal sense of "not physically bending" (as in an unbending rod) logically extended to the figurative character trait of being inflexible, rigid in opinion, or refusing to yield, completing its semantic journey from a physical property to a psychological one.
