### Clue: Einstein's resolved twenty-odd (and more) years ago, say (8)
### Answer: NINETIES 
 ### Explanation: Definition: twenty-odd (and more) years ago, say
  Anagram(*resolved*) of *EINSTEIN*.  Defn:  The 1990s were *twenty-odd years ago*, and the 1890s, etc. were twenty-odd and more years ago.  I think that's how to read the "*(and more)*" bit.
