Interpret negative things honestly (8)
I believe the answer is:
construe
'interpret' is the definition.
('construe' can be a synonym of 'interpret')
'negative things honestly' is the wordplay.
'negative things' becomes 'cons' (I can't explain this - if you can you should believe this answer much more).
'honestly' becomes 'true' (can be an adverb as in 'speak true', 'ring true').
'cons'+'true'='CONSTRUE'
Can you help me to learn more?
(Other definitions for construe that I've seen before include "Read - trounces (anag)" , "Translate" , "Make sense of -- trounces (anag)" , "Analyse language" , "Assign meaning, interpret" .)
