White flyer, wings of swan on bird carrying dog upwards (8)
I believe the answer is:
snowball
'white flyer' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe you can see a link between them that I can't see?
'wings of swan on bird carrying dog upwards' is the wordplay.
'wings of' says to hollow out the word (remove centre letters) (letters on the two wings removed).
'on bird' becomes 'lwo' (I can't justify this - if you can you should believe this answer much more).
'carrying' indicates putting letters inside.
'dog' becomes 'lab' (short for labrador).
'upwards' says the letters should be written backwards.
'swan' with its centre taken out is 'sn'.
'lwo' going around 'lab' is 'llabwo'.
'llabwo' back-to-front is 'owball'.
'sn'+'owball'='SNOWBALL'
Can you help me to learn more?
(Other definitions for snowball that I've seen before include "kind of bush with white flowers" , "Drink of advocaat and lemonade" , "Wintry missile - demonised by 17" , "It's thrown in winter fun (8)" , "Cold sphere" .)
