Make sense of arguments against? Correct (8)
I believe the answer is:
construe
'make sense' is the definition.
(I've seen this before)
'arguments against? correct' is the wordplay.
'arguments against?' becomes 'cons' (I've seen this before).
'correct' becomes 'true' ('true' is associated in meaning with 'correct').
'cons'+'true'='CONSTRUE'
'of' is the link.
(Other definitions for construe that I've seen before include "Make sense of -- trounces (anag)" , "Counters (anag) - interpret" , "Recounts in order to interpret or explain" , "Analyse syntax using counters" , "Assign meaning, interpret" .)
