'deadlock' originates from English, specifically the combination of 'dead' and 'lock', where 'dead' meant 'complete' and 'lock' meant 'a fastening mechanism'.

'deadlock' changed from the English word 'deadlock' in the 18th century and eventually became the modern English word 'deadlock'.

Initially, it meant 'a complete stop or standstill', but over time it evolved into its current meaning of 'a situation where progress is impossible due to a disagreement'.
