Interpret Origin of Species? That’s right (8)
I believe the answer is:
construe
'interpret' is the definition.
(I know that interpret can be written as construe)
'origin of species? that's right' is the wordplay.
'origin of species?' becomes 'cons' (I can't justify this - if you can you should believe this answer much more).
'that's right' becomes 'true' (associated in meaning).
'cons'+'true'='CONSTRUE'
Can you help me to learn more?
(Other definitions for construe that I've seen before include "Understand" , "Translate" , "Recounts in order to interpret or explain" , "Interpret in a particular way" , "Read - trounces (anag)" .)
