Express a point of view over coniferous tree (5)
I believe the answer is:
opine
'express a point of view' is the definition.
(I've seen this before)
'over coniferous tree' is the wordplay.
'over' becomes 'o' (cricket abbreviation).
'coniferous tree' becomes 'pine' (pine is a kind of coniferous tree).
'o'+'pine'='OPINE'
(Other definitions for opine that I've seen before include "Suggest" , "Suppose" , "Conjecture" , "State one's held view" , "Express one's opinion openly" .)
