non-intrusive

The word is a modern English compound formed by adding the negative prefix 'non-' to the adjective 'intrusive.' 'Intrusive' itself derives from the Latin verb intrudere, meaning "to thrust oneself in," which is composed of in- (into) and trudere (to thrust). The prefix 'non-' comes directly from Latin non, a straightforward adverb of negation. Thus, the literal construction "not thrusting in" logically evolved into the modern abstract sense of not interfering, not causing disruption, or not requiring physical penetration, reflecting a principle of minimal interference in both social and technical contexts.
