Declare one's view that nothing should be placed on the Christmas tree? (5)
I believe the answer is:
opine
'declare one's view' is the definition.
(I've seen this in another clue)
'nothing should be placed on the christmas tree?' is the wordplay.
I cannot quite understand how this works, but
'nothing' could be 'o' (looks like zero - 0) and 'o' is found within the answer.
'tree?' could be 'pine' (pine is a kind of tree) and 'pine' is located in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
'that' is the link.
Can you help me to learn more?
(Other definitions for opine that I've seen before include "Express one's view" , "Give opinion" , "Express one's opinion openly" , "Hold forth" , "State as one's opinion" .)
