The word "unmanned" is derived from the combination of two English words: "un-" and "manned".
The prefix "un-" is a common negative prefix in English, meaning "not" or "lack of". It is used to form words that convey the absence or opposite of something.
The word "manned" is the past participle of the verb "man", which originally meant to furnish with men or crew a ship, aircraft, or other vehicle or weapon. Over time, "manned" came to be associated with activities or operations carried out by humans, particularly in the context of transportation, exploration, or military operations.
Therefore, the word "unmanned" combines the negative prefix "un-" with "manned", indicating the absence or lack of human presence or control.
