Maybe ropiest answer! (7)
I believe the answer is:
riposte
'answer' is the definition.
(I know that riposte is a type of answer)
'maybe ropiest' is the wordplay.
'maybe' indicates anagramming the letters.
'ropiest' anagrammed gives 'RIPOSTE'.
(Other definitions for riposte that I've seen before include "Quick clever reply" , "Rejoin" , "Witty comeback" , "Sharp answer" , "Return thrust or repartee" .)
