'incorruptible' originates from Late Latin, specifically the word 'incorruptibilis', where 'in-' meant 'not' and 'corrumpere' (root 'rumpere') meant 'to spoil, break, or destroy'.

'incorruptible' changed from the Late Latin word 'incorruptibilis' and passed into Old French/Middle English forms before becoming the modern English 'incorruptible'.

Initially it meant 'not able to be spoiled or morally ruined'; over time the sense has remained largely the same but has broadened to cover both moral integrity and physical non-decay.
