Share view of deforestation's impact? (5)
I believe the answer is:
opine
'share view' is the definition.
Although both the answer and definition are verbs in their base form, I cannot see how one could define the other.
'of deforestation's impact?' is the wordplay.
'of' becomes 'o''.
'deforestation's impact?' becomes 'pine' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'o'+'pine'='OPINE'
Can you help me to learn more?
(Other definitions for opine that I've seen before include "Express one's view" , "Suppose" , "Suggest" , "State as one's belief" , "Think - express a view" .)
