Wrong rock concert sir succeeded leaving (9)
I believe the answer is:
incorrect
'wrong' is the definition.
(I know that wrong can be written as incorrect)
'rock concert sir succeeded leaving' is the wordplay.
'rock' indicates anagramming the letters (the solver must 'rock' the letters around).
'succeeded' becomes 's' (genealogical abbreviation).
'leaving' suggests deleting specific letters.
'concert'+'sir'='concertsir'
'concertsir' with 's' taken away is 'concertir'.
'concertir' is an anagram of 'INCORRECT'.
(Other definitions for incorrect that I've seen before include "Not accurate" , "Erroneous" , "Place of refuge" , "False, wrong" .)
