Etymology
The word "unmanned" is a straightforward English compound built from native Germanic elements. The core root "man," from Proto-Germanic mann- meaning "person," is first negated by the prefix "un-," a common Old English negation. The suffix "-ed" is then added, adapting the past participial form to create an adjective meaning "not having a person or people." Its earliest uses described places devoid of people, but its most prominent modern application, for vehicles and systems operating without a human crew, emerged powerfully with 20th-century aviation and space technology. This evolution perfectly illustrates how a simple, literal construction can acquire a highly specific technical meaning.
