The word "crewless" is derived from the combination of two elements: "crew" and "-less".
The term "crew" originally comes from the Old English word "crū", which meant a group of people or company. It later evolved to refer specifically to a group of people working together on a ship or aircraft. The word "crew" ultimately originates from the Old Norse word "krūa", meaning "to crowd or assemble".
The suffix "-less" is an English combining form that means "without" or "lacking". It is derived from Old English "-lēas", which represents the absence or deprivation of the word it is affixed to.
Therefore, "crewless" essentially means "without a crew" or "lacking a crew".
