To render unsolvable. To make impossible to solve.

"You burned five of my puzzle pieces, why did you have to go and deplicate my puzzle like that?"

Paradox Duplicate 

A duplicate created as a result of time travel. When one object travels to another time where that same object also exists, then two of the exact same object occupy the same time. The popular theory is that one of the paradox duplicates is doomed to destruction as a result of the universe attempting to correct this violation of the reality matrix of existence. More pressing is the belief that, were the duplicates to come in contact with one another, it would violate the very basic law of physics that 'no two objects can occupy the same space at the same time', and, thus, unmake the universe.

"That's why i didn't want us to meet, Fry. We're paradox duplicates. The more we stayed away from each other, the better chance we had of staying alive. I guess I was wrong...(cough)"

deduplication 

This is a new computer scheme to reduce data.
Deduplication is the process of removing duplicate data, but remembering where it is. This way, multiple copies are usable, but take up the space of only one.

Damn dawg, my tape backup size is going crazy, I'm thinking about setting up some deduplication in this bitch to reduce backup and restore times for the man!

dewplicate

Phony outdoor-moisture drops dat look like da real deal, but were just artificially applied to one or more objects.

Bringing an item into a warm room from a cold one can create a great dewplicate on its surface, even though da object never left da house.
