Thought about bird’s proposal (10)
I believe the answer is:
nomination
'proposal' is the definition.
(thesaurus)
'thought about bird's' is the wordplay.
I cannot really see how this works, but
'about' could be 'on' (as in a book 'on' a certain topic) and 'on' is found in the answer.
'bird' could be 'mina' (alternative spelling of myna) and 'mina' is present in the answer.
The remaining letters 'noti' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for nomination that I've seen before include "Putting forward (of a candidate)" , "Naming" .)
