The end of Victor Hugo turned out hard (5)
I believe the answer is:
rough
'hard' is the definition.
(similar in meaning)
'the end of victor hugo turned out' is the wordplay.
'the end of' indicates one should take the final letters.
'turned out' is an anagram indicator.
The final letter of 'victor' is 'r'.
'hugo' is an anagram of 'ough'.
'r'+'ough'='ROUGH'
(Other definitions for rough that I've seen before include "Ill" , "Delinquent" , "The long grass on the golf course" , "Approximate; turbulent" , "'Coarse, rugged (5)'" .)
