The state or quality of being outside or external to something.

Exteriority → It is formed from "exterior" (from Latin "exterior" meaning outer or external) and "-ity" (meaning the state or condition of). The word "exteriority" refers to the state of being external or outside.
Think of 'exterior' meaning outer, and '-ity' indicating a state — so exteriority is the state of being outside.
