Spread wings? These do (11)
I believe the answer is:
butterflies
'these do' is the definition.
The definition suggests an adverb but the answer is not.
'spread wings?' is the wordplay.
'spread' becomes 'butter' (butter is a spread).
'wings?' becomes 'flies' ('fly' can be a synonym of 'wing').
'butter'+'flies'='BUTTERFLIES'
Can you help me to learn more?
(Other definitions for butterflies that I've seen before include "Nervous sensation" , "Nervous feeling in stomach" , "Nervous tremors in the stomach" , "coppers?" , "Skippers, for example" .)
