Wild idea: share opinion with God (7)
I believe the answer is:
chimera
'wild idea' is the definition.
(I've seen this before)
'share opinion with god' is the wordplay.
'share opinion with' becomes 'chime' (I can't explain this - if you can you should give a lot more credence to this answer).
'god' becomes 'Ra' (Egyptian god).
'chime'+'ra'='CHIMERA'
Can you help me to learn more?
(Other definitions for chimera that I've seen before include "Fire-breathing female monster" , "Lion-headed monster" , "Mythological animal; something illusory" , "fabulous creature" , "Mythical monster, part lion, goat and serpent" .)
