Nonencapsulated → It is formed from "non-" (meaning not), "encapsulate" (from Latin "capsula", meaning a small box or container, combined with "in-" meaning in and "capere" meaning to seize or take), and "-ed" (indicating a state or condition). The word describes something that is not contained or enclosed within a capsule or boundary.
Think of 'not' ('non-') being used to describe something that is 'not contained' ('encapsulated') — this helps you remember that nonencapsulated means something that is free or open.
