'error-resilient' originates from the combination of 'error' and 'resilient', where 'error' refers to a mistake or fault, and 'resilient' means able to withstand or recover quickly from difficult conditions.

'error' comes from Old French 'errer', and 'resilient' comes from Latin 'resilire', meaning 'to leap back'.

Initially, 'resilient' meant 'to leap back', but over time it evolved to mean 'able to withstand or recover quickly from difficult conditions'.
