'corruptible' originates from Latin, specifically the word 'corrumpere', where 'com-/cor-' meant 'together/with' and 'rumpere' meant 'to break', giving a sense of 'spoil' or 'destroy'.

'corrumpere' passed into Old French as 'corrompre' and Middle English as 'corrupten'/'corrupt', and the adjective form developed into modern English 'corruptible'.

Initially it was connected to the idea of 'breaking' or 'spoiling'; over time it came to mean 'able to be morally or structurally spoiled or altered', now expressed as 'able to be corrupted'.
