Years after corruption in genre, it's E for Einstein? (6)
I believe the answer is:
energy
'e for einstein?' is the definition.
(I've seen this in another clue)
'years after corruption in genre' is the wordplay.
'years' becomes 'y' (abbreviation).
'after' means one lot of letters go next to another.
'corruption in' indicates anagramming the letters (I've seen this in other clues).
'genre' is an anagram of 'energ'.
'y' after 'energ' is 'ENERGY'.
'it's' is the link.
(Other definitions for energy that I've seen before include "Healthy capacity for vigorous activity" , "life" , "Vigour, vim, vitality" , "Gusto" , "Exertion of force" .)
