I see that *interrupt* morphologically and semantically means 'to break something intermittently'. 

I see that *corrupt* is formed from prefix 'co-' (which I know means "(put) together") and 'rupt' which stands for 'disruption' or 'break'. How do you break the stuff by putting its parts together? This sounds like oxymoron.

How can I understand the etymological roots of the word *corrupt*?
