the word 'unmoving' is a modern english formation built upon the well-established verb 'move'. the core root 'mov' descends from the latin verb 'movēre', meaning "to set in motion," which itself has deep proto-indo-european ancestry in the root meue-, also signifying motion. the negative prefix 'un-', of old english origin, is one of the most common and productive means of forming opposites in english. the suffix '-ing', also from old english, is used to create adjectives that describe a state or characteristic. thus, the literal construction "not-moving" directly and logically yields the modern meanings of being physically stationary or emotionally steadfast.
