'crewless' originates from the English word 'crew' combined with the suffix '-less', where 'crew' meant 'a group of people working together' and '-less' meant 'without'.

'crew' changed from the Middle English word 'crewe' and eventually became the modern English word 'crew'.

Initially, it meant 'without a group of people working together', and this meaning has largely remained the same in modern usage.
