the word 'untethered' is a relatively modern english formation built upon the older noun 'tether'. 'tether' itself entered english from old norse, a language spoken by viking settlers, where it referred to a rope for fastening animals. the core concept of physical restraint was extended metaphorically to describe abstract limitations. by adding the old english negative prefix 'un-' and the adjectival suffix '-ed', the word literally constructs the meaning "not having a tether," evolving from a description of a physically unrestrained animal to a person or concept free from restrictions.
