I am unable to come up with a complete solution. No outside knowledge is said to be required for the solution to this puzzle.
- words which are not without a prefix only have ré as their prefix.
- words whose meaning remains the same with or without a prefix have ré as a prefix.
- words which don't include m and only 'a lot of' n have ré as their prefix.
None of these lead to a complete solution. How can this be solved?
