🎤Pronunciation
🌳Etymology
Origin
Unmanned combines the negating prefix 'un-' with 'man' (person) and the past participle suffix '-ed' to denote the absence of human operators. The term gained widespread usage during twentieth-century space exploration, particularly describing spacecraft and vehicles operated remotely or autonomously without human crews.
Breakdown
un- (not, negation) + man (person) + -ed (past participle/adjective suffix). The formation follows English productive morphology, where 'un-' negates the adjective 'manned' (crewed by people) to produce 'unmanned' (lacking human operators).
