Etymology
the word 'fixity' is a relatively modern formation, entering english in the mid-17th century. it is constructed from the established english verb 'fix', which itself descends from the latin figere (to fasten, attach), a verb with probable proto-indo-european roots related to piercing or fastening. the suffix '-ity', borrowed via old french from the latin abstract noun-forming suffix -itas, is systematically appended to adjectives (and sometimes other roots) to denote an abstract state or condition. therefore, 'fixity' logically builds upon the concrete action of 'fixing' something in place to express the abstract quality of being fixed, stable, and resistant to change.
Analysis
fix (from latin fixus, past participle of figere meaning 'to fasten, fix'; serves as the core root conveying the sense of making firm or stable). ity (from latin -itas, a suffix forming abstract nouns indicating a state or quality; serves as a nominalizer).
