Old parrot cradling wing? One seeks assessment (7,4)
I believe the answer is:
opinion poll
'assessment' is the definition.
Both the definition and answer are singular nouns.
Maybe they are linked in a way I don't understand?
'old parrot cradling wing? one seeks' is the wordplay.
I cannot really see how this works, but
'old' could be 'o' (common abbreviation eg in OE for Old English) and 'o' is found in the answer.
'parrot' could be 'poll' (poll is a kind of parrot) and 'poll' is located in the answer.
'wing?' could be 'pinion' ('pinion' can be a synonym of 'wing') and 'pinion' is found in the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for opinion poll that I've seen before include "Survey of public views" , "Test of voting intentions" , "Sounding" , "Test of voting intention" .)
