Interpret as disadvantages? Right (8)
I believe the answer is:
construe
'interpret' is the definition.
('construe' can be a synonym of 'interpret')
'disadvantages? right' is the wordplay.
'disadvantages?' becomes 'cons' (as in pros and cons).
'right' becomes 'true' ('true' is associated in meaning with 'right').
'cons'+'true'='CONSTRUE'
'as' acts as a link.
(Other definitions for construe that I've seen before include "Analyse syntax using counters" , "Make sense of -- trounces (anag)" , "Analyse language" , "Recounts in order to interpret or explain" , "Read - trounces (anag)" .)
