Derived from Latin derelictus, the past participle of derelinquere ("to abandon"), combining de- (intensifying "away") and relinquere ("to leave"). The word originally described physical abandonment (e.g., ships) and later expanded to moral neglect. The dual meaning reflects both tangible and abstract desertion.
